The best Android tablets 2023, buying guide
The best Android tablets are great alternatives to the iPad .
The best Android tablets are well-designed devices with enough power to run apps and games with minimal slowdown. They are also efficient enough to last a long time on a single charge. And with the addition of a keyboard, some Android tablets can be as reliable as laptops.
When it comes to Android tablets, Samsung dominates the market by offering a large number of apps. However, if you’re an Amazon dedicated user looking for a portable device to enjoy your favorite Prime content on the go, Fire tablets are a great choice.
To help you find the right Android tablet, we tested many of them in the lab, measuring battery life and performance, as well as screen quality. When it comes to app quality, we’ve found that your decision may come down to how many apps a tablet offers — and not all Android tablets have the same apps.
Without further ado, here are the best Android tablets, based on hands-on tests and reviews of dozens from Amazon, Samsung, Nokia, and even OnePlus.

Why should we buy the Lenovo Yuka Tab 13 tablet?
- Built-in base
- Very clear 13 inch touch screen
- Impressive speakers
- Long battery life
Why should we buy the Lenovo Yuka Tab 13 tablet?
- Lack of 5G support
- No rear camera
- It is difficult to find suitable cases for it
Our fourth pick for the best Android tablets, the Lenovo Yoga Tab 13 is an entertainment-focused Android tablet with an impressive 13-inch display and quality speakers. It makes you feel like you are watching movies and shows on a proper TV instead of a bulky tablet. Thanks to the fast Snapdragon 870 processor and 8 GB of memory, playing games is also a pleasure. The tablet can even act as a secondary monitor for your laptop or tablet, giving its 2K display a bit more versatility.
While it’s great at what it does, it’s not the most portable device out there. It is also impossible to find a protective cover due to its unusual design. The lack of 5G support and the absence of a headphone jack are also disadvantages of this tablet. However, if you’re looking for an entertainment-focused tablet that you’re not going to buy, the Yoga Tab 13 is a good choice.

Why should we buy the Amazon Fire 10 HD 2021 tablet?
- Stellar battery life
- Clear and bright screen
- USB-C charging
Why should we not buy the Amazon Fire 10 HD 2021 tablet?
- The speakers are not that strong
- It doesn’t have Google apps yet
The Amazon Fire HD 10 (2021), the fifth best Android tablet of 2023, takes an already good tablet and applies incremental updates, such as a slightly brighter screen, 1GB more RAM, and a smaller design. and lighter While this tablet probably isn’t a must-buy for anyone who bought the 2019 model, it does show Amazon’s ability to deliver a value-oriented screen that’s good enough for many.
If you think you’ll be bothered by the slight lag in performance, you’ll want to spend an extra $30 on the $179 Amazon Fire HD 10 Plus, which is arguably the best Amazon tablet you’ll ever buy. However, the Fire HD 10 (2021) will still be great for people looking for a device to casually browse the internet, read e-books, and watch videos. This makes the Fire HD 10 among the best Android tablets available, and one of the best tablets you can buy—especially if you’re on a budget.
However, its biggest flaw is nothing new. Most importantly, Amazon’s Fire OS is still challenging and missing the Google Play Store — meaning you can’t get the full YouTube experience, for example, and you’ll miss out on many great apps that aren’t available on Amazon.
Technical Specifications
Why should we buy the Amazon Fire HD 8 tablet?
- Amazing battery life
- Bright screen
- USB-C port
Why should we not buy the Amazon Fire HD 8 tablet?
- There is no Google app yet
- Pay to remove Amazon ads
Our sixth pick on the best Android tablets 2023 is the Amazon Fire HD 8. If someone asks me for tablet recommendations and their budget is too tight for an iPad, I’ll probably ask if they subscribe to Amazon Prime. The Amazon Fire HD 8 is the best Android tablet for those who love a good deal because it’s a great deal at just $90.
Its impressive 13+ hour battery life stands out in a sea of tablets we already complement for endurance, and yes, you can get a reversible USB-C port at this wallet-friendly price. Even its selfie camera is very decent, rivaling the webcams of more expensive laptops.
The Amazon Fire HD 8 comes without some of the other basics you might expect when you hear “Android tablet.” You don’t have the Google Play Store, along with many great podcast apps, on this tablet. Yes, that means the YouTube and Gmail apps can’t be used on this tablet, and you’re forced to access the web browser versions of these standard services in Amazon’s mostly acceptable Silk web browser.
Technical Specifications
Why should we buy the Samsung Galaxy Tab S7 tablet?
- Great battery life
- Beautiful 120 Hz screen
- Thin and light design
Why we should not buy the Samsung Galaxy Tab S7 tablet
- The book cover keyboard has a compact layout
- DeX mode still has room for improvement
Our seventh pick on the best Android tablets 2023 is the Samsung Galaxy Tab S7. Android tablet lovers needed it before they even knew the Samsung Galaxy S7 existed. This beautiful tablet is thin, light and has narrow bezels for the full-screen beauty that Apple has been offering users for years with the iPad Pro. The Tab S7’s screen is so bright and colorful you’ll want to use it for your next Netflix binge. And more than 13 hours were spent in our battery life test. On top of that, you get a windowed Android app experience in DeX mode (which could use some polish), but it’s more than adequate for getting the job done.
However, we want more from the Tab S7’s book cover keyboard ($199 extra). Its number keys will be too small for some, and if you frequently switch from laptop to tablet mode, the two-piece design assembly is a little annoying. Also, we wish the Snapdragon 865 Plus was a bit more in its stride, as benchmarks show that Intel’s Core i5 and Apple A12Z chips are running amok. So while some opt for cheaper (and still good) Android tablets, the Galaxy Tab S7 is the high-end tablet that Android users deserve.
Technical Specifications
Why should we buy the Samsung Galaxy Tab S8 Ultra tablet?
- Large and beautiful OLED screen
- Stylish design
- Snappy Android interface
Why should we buy the Samsung Galaxy Tab S8 Ultra tablet?
- May be too big for some
- More expensive than better laptops
Our final pick for the best Android tablets of 2023, the Samsung Galaxy Tab S8 Ultra ($1,099) is the first tablet to literally overshadow the iPad Pro . With its gorgeous 14.6-inch OLED display, this Android slate makes the 12.9-inch iPad Pro look beautiful in comparison. And with optional keyboard connectivity and improved multi-window mode, the Galaxy Tab S8 Ultra could potentially replace a laptop.
Samsung is clearly targeting hybrid and home options with the Galaxy Tab S8 Ultra, as it packs dual front-facing cameras with support for up to 4K resolution for video calls, as well as auto-framing to keep you in frame on the go. Plus, there’s advanced noise reduction to make sure you get through loud and clear.
Other highlights of the Tab S8 Ultra include the fast Snapdragon 8 Gen 1 chip, a low-latency S Pen experience, 45W fast charging, and improved integration with the Galaxy S series phones.
The Galaxy Tab S8 Ultra is priced high at $1,099. But it offers an intoxicating combination of size, speed and versatility that makes it one of the best tablets on the market.
How to choose the best Android tablet for you
When it comes to choosing the best Android tablet for you, start by thinking about the apps you want. Yes, the battery life and performance on many of these tablets are so similar that you could easily cross off half of this list wondering if you’ll need your next Android tablet for anything beyond Netflix and Spotify. do.
Those who want every single app on their Android phone should probably look at the Amazon Fire tablets, as those require jumping through hoops (and disabling security features) to get Gmail or any of Google’s apps as apps. If you don’t need those apps on your tablet, or you can use older, less-than-stellar versions of those apps in a web browser, you might want to consider Fire tablets.
If you want all the apps, you have three questions, each with its own answer. Do you mainly consume content? Get the Galaxy Tab S6 Lite. Are you looking for a device where you can publish a Word document and possibly replace your laptop? Galaxy Tab S6 is right for you. Looking for a tablet to share with the family? Huawei MediaPad M5 Lite is the best option for you.
Those who are comfortable with the limitations of Amazon’s tablets should opt for the Fire 7 for less demanding uses, and the Fire HD 8 if buying for those with slightly higher standards. And if you’re looking for the best of the budget, the Fire HD 10 is for you.
How do we test Android tablets?
The first thing we do to separate the big tablets from the jokers is to test all their different aspects. Our web-based battery test is how long a tablet can browse the web, with its display set to 150 nits of brightness. But to find out what percentage of brightness equals 150 nits, we run a series of display tests to measure how colorful the panel is (as measured by the sRGB output number) as well as how bright it is. Next, we run benchmark tests on said tablet, including the latest version of Geekbench’s general performance benchmark.
Another thing we do when evaluating Android tablets is check the app store to see if you’re getting a real Android experience or a company’s take on it. The latter is a huge disappointment – although we expect nothing different from Amazon at this point. On tablets with parental controls settings, we try to find loopholes in said restrictions before your kids can spot red flags.
Then, we just use the tablets as if we owned them. We open tab after tab and program after program to see if we can multitask without problems. We also watch YouTube videos because the color output (sRGB) and brightness (nits) measurements don’t tell the whole story. Only through all these tests can we be sure to give you a complete assessment of the tablet’s value.

MacBook Air M3 review; Lovely, powerful and economical

06/05/2024MacBook Air M3 review; Lovely, powerful and economical
If you are looking for a compact, well-made and high-quality laptop that can be used in daily and light use, the MacBook Air M3 review is not for you; So close the preceding article, visit the Zomit products section and choose one of the stores to buy MacBook Air M1 ; But if you, like me, are excited to read about the developments in the world of hardware and are curious to know about the performance of the M3 chip in the Dell MacBook Air 2024 , then stay with Zoomit.
The design is a copy of the original from the last generation
Almost two years have passed since Apple said goodbye to the familiar and wedge-shaped MacBook Air design; A different design that accompanied this ultrabook from the first day of its birth in 2008; But finally in 2022, with the aim of harmonizing the design language of the Apple laptop family, it was abandoned so that the MacBook Air 2022 will have a similar appearance to the 14-inch and 16-inch MacBook Pro.
The new MacBook Air is uniform in thickness; But it was slimmer, the screen was bigger, the edges were narrower and the corners were rounded, and a relatively large notch was added to it, whose only existence was to host the device’s 1080p webcam. MacBook Air 2022 also marked the return of the MagSafe magnetic charging port to Apple’s popular Ultrabook.
Previously, in the review of the MacBook Air 2022 with the M2 chip, we have talked comprehensively and deeply about its design and its positive and negative points. I suggest that if you haven’t read the article, you must visit it; Because the MacBook Air M3 is no different from the MacBook Air M2 in terms of appearance, display, or ports.
We also see the same incredibly well-made and metal body of MacBook Air 2022 in the new generation of Apple Ultrabooks; A body that, like the rest of Apple laptops, is carved from an aluminum block instead of the usual method of using aluminum sheets, and for this reason, it has a strong and dense structure so that we do not see the body sinking when pressing the keyboard area or the screen frame swinging.
All the parts of the MacBook Air 2024 are assembled with the utmost care; So that there is no gap between them. As expected, the hinge of the laptop is also well-adjusted so that you don’t need to use two hands to open the laptop door. All in all, the combination of the quality of components and Apple’s exemplary engineering precision, brings an extremely enjoyable and unique feeling to the user while using the MacBook Air.
Just like the previous generation, the new MacBook Air is sold in four colors: gray, silver, dark blue, and cream. One of the flaws that could be found in the design of the MacBook Air 2022 was that fingerprints and grease remained on the body; The item that was more noticeable in dark blue color. Apple says this year it has used a new coating that reduces the severity of this problem. We did not have the 2022 model available for comparison at the time of writing the following review, But traces of fat and finger still remain on the body of the MacBook Air 2024.
Grease and fingerprints on the laptop body
MacBook Air keyboard is among the best examples in the market in terms of arrangement and dimensions, feedback, and key stability; But the matte coating on the keys absorbs the fat of the fingers very quickly, and on the other hand, like other MacBooks, there is a possibility that the matte coating will disappear and the keys will become shiny. Depending on your usage, this can happen very quickly or over time; For example, for me, who is constantly writing, the keys on my MacBook Pro M1 burned out in less than a year.
Apparently, the buyers of used laptops are very sensitive about the keys being electrocuted; Therefore, if you plan to replace your Macbook with another laptop after one or two years, be sure to keep this in mind and use an external keyboard for long typing.
As always, the trackpad is one of the main strengths of any MacBook, and the MacBook Air M3 follows the same rule. The glass trackpad of the device is large in size and has little friction on its surface, it offers flawless, accurate, and smooth performance, and its Fortouch mechanism, which makes it possible to click on the entire surface of the trackpad, is so efficient that after the MacBook, it is impossible to work with the trackpad of any laptop. Another enjoyed.
MacBook Air 2022
The set of MacBook Air 2024 ports is limited and has not changed; On the right side of the device, there is a headphone jack, and the left side of the device hosts two USB4 ports and a MagSafe magnetic charging port. Along with the basic model, Apple provides a relatively small 30-watt adapter with a cloth cable of the same color as the device’s body; But you can also get the laptop with a more powerful 35 or 70-watt adapter, which charges the battery up to 50% within half an hour.
USB4 ports support Thunderbolt 3 standard with a bandwidth of 40 Gbps, But it is not possible to connect external graphics. Both ports also transmit the image signal with the DisplayPort standard. In the new MacBook, if you close the laptop door, you can connect a 6K monitor and a 5K monitor (both 60Hz) to the device at the same time; But with the laptop’s screen on, just like the MacBook Air M2, the image output is limited to a 6K monitor; It is interesting that the Intel version of MacBook Air could output images to two 4K monitors at the same time as its own screen is on!
As in the previous generation, Apple uses Bluetooth version 5.3 in its Ultrabook; But the Wi-Fi module has upgraded the device from Wi-Fi 6 to Wi-Fi 6E, which incompatible networks can increase the communication bandwidth of MacBook Air 2024 with the router and the rest of the devices in the network from 1.2 to 2.4 Gbps.
Attractive display with more attractive competitors
Like most parts of the device, the screen of the new MacBook Air does not change; Of course, in this field, you can’t criticize Apple much, since 2018, when the MacBook Air screen became Retina, it has always been among the best; However, today, with OLED competitors with stunning colors and infinite contrast, Apple’s Retina display no longer has its former glory.
MacBook Air M3 can be purchased just like the previous generation in two 13.6-inch and 15.3-inch models. The pixel density of both versions is a very good number of 224 pixels. With this density, the MacBook Air screen produces a very clear image. So that it is difficult to distinguish the pixels from each other. We have the 13.6-inch MacBook Air M3 with a resolution of 2560 x 1664 pixels available for review.
Unfortunately, unlike the expensive models of MacBook Pro or even Windows Ultrabooks with the same price as Zenbook, the panel of the MacBook Air is 60 Hz and it does not have amazing technologies such as OLED and MiniLED to produce 1000 nits of brightness and extraordinary colors. MacBook Air uses an 8-bit IPS LCD panel with back exposure, which, by using FRC technology, can give the user the feeling of 10-bit panels with a billion colors.
MacBook Air covers the wide DCI P3 color space with high accuracy. The Apple Ultrabook covers 98.4% of this space with an error of 1.9 (an error of less than 3 is ideal), perhaps the only color weakness of the panel can be considered a slight tendency to be cold; However, thanks to the True Tone feature, the device evaluates the ambient light temperature with high accuracy and adjusts the color temperature accordingly to give you a satisfying visual experience.
In our measurements, with a 50% raster standard, we reached a maximum brightness of 443 nits, which in itself is a very good number, and thanks to the anti-reflective coating on the panel surface, in environments with different light conditions, it brings a satisfactory experience of working with a laptop. Without the appearance of the shadow of the environment on the panel, the user will not be bothered.

In addition to the reasonable maximum brightness of 442 nits in bright images, unlike most laptops with IPS LCD screens, the black color brightness is also very low in the MacBook Air display; So that the device achieves a very high contrast. On the other hand, the minimum brightness of the display was 0 nits even with the 0.01 nits accuracy of the Zoomit luminance meter; In the sense that while using the laptop, there will be a little pressure on your eyes.
The attractive screen of the MacBook Air is completed by a set of 4 speakers; Speakers that have a very large sound volume compared to the size of a laptop, produce clear sound, and at high volumes, they are confused and distorted. MacBook Air speakers support Dolby Atmos and are easily ahead of most Windows laptops.
M3 chip and championship called TSMC
The main changes of MacBook Air 2024 have happened in its heart; Where it hosts the M3 chip as the beating heart of the device. Next, before we put the performance of the M3 under the microscope, we take a look at the details of the technical specifications of this chip.
The M3 chip is manufactured using TSMC’s 3nm-based manufacturing process known as N3B, hosts 25 billion transistors on its surface, and uses the same layout and configuration as the M2 for the CPU and GPU cores. Apple says the processor and graphics used in the M3 are about 35 and 65 percent faster than the M1, respectively.

Like the last two generations, the M3 chip uses a combination of 4 high-power cores and 4 low-power cores, respectively, with maximum frequencies of 4.05 and 2.75 GHz as CPU. Apple has made minor changes in the architecture of the cores, and the main difference of the cores is the 15% increase in frequency compared to the M2 cores.
Apple has not even changed the amount of cache memory of the M3 chip compared to the M2; Each of the high-power and low-power cores have access to 320 and 192 KB of ultra-fast L1 cache, respectively, the set of four high-power and low-power cores also have access to 16 and 4 MB of L2 cache, respectively, while the system cache is 8 MB for the set of chip processing blocks. GPU and CPU are included.
The M3 chip is used in Apple laptops in two versions with 8- and 10-core graphics processors. We had the MacBook Air with 8-core graphics available for review, which in total, just like the last generation, has 128 execution units with 1024 calculation and logic units in its heart, which operate at an almost identical frequency of 1.38 GHz.
The main difference between the M3 graphics compared to the previous generation is the addition of the Ray Tracing hardware accelerator, Mesh shading, and Dynamic Caching technology, the latter of which allows the chip to provide the memory required by the GPU in real-time and based on the type of processing. Thus, it optimizes the amount of memory consumption.
The M3 chip uses a 16-core neural processing unit (NPU) with a computing power of 18 trillion operations per second, and in addition to ProRes and ProRes Raw videos, it now has a separate engine for AV1 video codec decoding. Due to its two 64-bit channels and support for LPDDR5X-6400 RAM, this chip can achieve a bandwidth of 102 GB/s for data exchange with its integrated RAM.

MacBook M3 appears about 20-25% faster than M2 in single-core and multi-core benchmarks, and in comparison with M1, it increases its superiority to about 35-45%; Therefore, considering the 15% increase in frequency and the improvement of TSMC’s manufacturing process, it seems that Apple has not changed much in the architecture; But in any case, CPU performance on par with the M1 Pro is a surprising result for the M3.
Compared to the new Asus ultrabook with the Core Ultra 7 155H chip, MacBook Air M3 leads by 15-35% in single-core benchmarks; But in multi-core benchmarks, it loses the field to the competitor with a single-digit difference of up to 25%. We will talk more about the difference between the two chips in productivity and power consumption.
Apple laptops have a stunning performance in terms of web surfing experience and M3 has taken this performance to a whole new level; MacBook Air 2024 outperforms Asus Ultrabook 2024 with a 65% difference in the Zoomit web browsing test. The stunning superiority of the MacBook Air shows that Apple’s laptop offers faster and smoother performance on the web.
Apple’s new ultrabook appears in almost the same level of computing processing as the last generation. It seems that M3 remains behind its Intel competitor by 25% in the processes that take place on the basis of the OpenCL framework; But instead, thanks to Apple’s exclusive Metal framework, it surpasses the performance of Core Ultra 7 in processes based on Vulkan, with a difference of 10%.
Let’s skip the benchmarks and talk about how the MacBook Air 2024 performs in professional software and games. For this, we considered Photoshop and Premiere Pro software, Python code execution, and the Rise of the Tomb Raider game.
The set of games available for macOS is much more limited than for Windows; However, thanks to the tool that Apple introduced at WWDC 2023 for porting Windows games (Game Porting Toolkit), some were able to run titles such as Medium and Cyberpunk 2077 on Macs with powerful graphics processors such as the M2 Max, and it is hoped that in the future, this same tool, pave the way for more games to be released.
We were able to run the old game Rise of the Tomb Raider at 1200p resolution, High graphics settings and an average frame rate of 50.5 fps, which shows an advantage of about 25 percent of the M3 compared to the M2.
MacBook Air M3 performance while playing Rise of the Tomb Raider game
MacBook Air M3 works about 10 to 20 percent faster than its two previous generations and ZenBook 14 while using Photoshop software for tasks such as resizing large photos and implementing the blur effect or lens correction.

In Premier Pro software, while performing tasks such as blur effect implementation, image sharpening, or 4K video output, the performance of the device is 20-30% better than the MacBook Air M2 and Zenbook 14.
Performance of MacBook Air M3 in Premier Pro software
Note that in software such as Premiere Pro, where we are dealing with heavy projects, the low RAM overshadows the performance level and you may even get stuck in scenarios like editing 4K videos. Next, we will talk about the MacBook Air M3 RAM.
The MacBook Air was able to run Zoomit’s Python code in about 45 seconds, which is about 13 seconds faster than the M2 and 33 percent faster than the M1.
MacBook Air M3 performance while running Python code
One of the most attractive features of MacBooks is that they work equally well, whether connected to electricity or relying on batteries; For example, when running Python code while plugged in, the MacBook Air M3 beats the ZenBook 14 by just 4 seconds; But by disconnecting the laptops from the electricity and Zenbook’s performance drop, the time difference reaches 11 seconds!
In addition to running Python code, the MacBook Air also displays similar performance in other software in both plugged-in and battery-powered states; In the table below, you can see the difference in performance of MacBook Air M3 in Plugged and UnPlugged modes in a number of users:

In the MacBook Air 2022 review, we said that the lack of an active cooling system (fan) makes this ultrabook unable to provide stable performance under continuous processing loads. Now it’s time for MacBook Air 2024 with the same cooling system; But this time with a more optimized chip, it will be wider. Does the MacBook Air M3 offer stable performance?
To evaluate the cooling system, the performance stability level and measure the power consumption and other parameters of the MacBook Air M3, we first ran the CineBench R23 multi-core test on the device for 30 minutes consecutively in both power-connected and battery-based modes; Then we went to the 20-minute Wild Life Extreme test.

MacBook Air M3 shows more or less the same behavior whether in Plugged or UnPlugged mode; After 30 minutes, the CPU performance drops by about 15-20%, and in a 20-minute graphics processing load, the GPU drops by 25%.
Contrary to the numbers stated in the technical specifications of the M3 chip, the MacBook Air 2024, whether in multi-core or single-core processing, never reaches the frequency of 4.05 GHz in powerful cores; In my measurements, the frequency of the most powerful cores in the multi-core test remained at 3.7 GHz for a few seconds; But it immediately begins the gradual process of decline and reaches below 2.5 GHz from the 10th minute, which is lower than the stable 2.75 GHz frequency of low-power cores!

CPU frequency in MacBook Air M3
The frequency drop process starts when the temperature of the hottest point of the chip reaches 103 degrees Celsius; It seems that Apple has adopted a more conservative strategy this year; Because in MacBook Air M2, the maximum temperature of the chip reaches 109 degrees Celsius. The temperature of 103 degrees of the chip continues for 5-6 minutes and then, thanks to the frequency drop, it decreases to the range below 90 degrees Celsius.
CPU temperature on MacBook Air M3
The temperature of the laptop body rises to 46-47 degrees Celsius, especially in the upper area of the keyboard; But in general, the body heat is not such that you cannot continue working with the laptop.
CPU consumption in MacBook Air M3
As you can see in the power consumption graph, the CPU consumes about 21 watts in the first few seconds; But as the body heats up, the power consumption gradually decreases and after a few minutes it reaches below 10 watts and reaches the range of 7-8 watts.
As you can see from the graphs below, the M3 GPU also follows a similar path to performance degradation from overheating the device.
GPU consumption in MacBook Air M3
GPU temperature on MacBook Air M3
GPU frequency on MacBook Air M3
About 2-3 minutes after the start of graphic processing, in order to prevent the chip temperature from exceeding 103 degrees Celsius, the frequency of the GPU drops from about 1350 MHz and its power consumption from about 14 watts to 1000 MHz and below 8 watts. is approaching
My tests show that the MacBook Air M3 uses its powerful core stably with a frequency of about 3,750 MHz in single-core processing, this number is about 3,200 and 2,980 MHz in the MacBook Air M2 and MacBook Air M1 laptops, respectively.
In order to have a general outline and limits of architecture changes and IPC (the number of instructions executed per processing cycle), we can divide GeekBench’s single-core score by the chips’ single-core frequency; Note that this measure is not exact and only provides a general picture of the state of architectural changes. To accurately measure IPC, one should go to an expensive tool such as SPECView, which unfortunately is not available in Iran.
Ratio of performance to CPU frequency
To be more precise, what you see in the graph above is the ratio of single-core performance to CPU frequency in three generations of MacBook Air laptops with M1, M2, and M3 chips. In this chart, I have considered the MacBook Air M1 as a benchmark so that we can compare the other two chips relatively. The numbers say that the architectural changes in M3 have a 4 and 7 percent impact on the performance of this chip compared to M2 and M1, which is not a significant improvement.
In the graph below, you can see the ratio of M3’s performance to its power consumption compared to previous generations and the Core Ultra 7 155H chip. Note that the amount of power consumed by the chips is not stable and after a few seconds, it deviates from its maximum value; Therefore, the graph below was created by running CineBench R23 once and based on the average power consumption during the benchmark execution period, so that we can obtain the ratio of performance to power consumption in the best performance condition of the laptop.
The ratio of performance to CPU power consumption
My measurements show that the M3 consumes an average of 4.9 and 19.1 watts when running the CineBench R23 single-core and multi-core benchmarks, respectively; While these numbers are equal to 8 and 20.2 watts for the M2 and 23 and 37.8 watts for the Core Ultra 7 155H, respectively, this shows the stunning efficiency of the M3; But if you consider the numbers obtained in the previous chart, you will realize that TSMC’s optimized manufacturing process has more influence on this amazing productivity than IPC and Apple’s architecture improvements.
The M3’s incredible efficiency also contributes to the MacBook Air M3’s excellent charging performance. Apple uses the same 52.6-watt-hour battery as the MacBook Air M2 in its new ultrabook and says that this laptop can charge for about 18 hours, just like the previous generation.

The MacBook Air 2024 was able to play our benchmark HD video for a little over 14 hours, just like the previous generation, in standard Zoomit conditions, which includes 200 nits brightness (about 70% brightness) and flight mode activation, which is an impressive result; But it is about 3 hours less than the Asus Zenbook 14 Ultrabook with a larger 75 watt-hour battery.
… and 8GB RAM for everyone
Unfortunately, this year Apple did not fall short either, and in 2024, it released the basic version of its $1,100 ultrabook with 8 GB of RAM and 256 GB of SSD. If you buy from Apple’s website, you can order 16GB or 24GB of RAM and 512GB, 1TB, and 2TB of SSD; Of course, to go to each higher step, you have to pay 200 dollars more; For example, the MacBook Air 2024 with 16 GB RAM and 512 GB SSD will cost you about $1,500.
If the base version of the 8GB MacBook Air disappointed you, you can be glad that Apple has moved away from the cowardly strategy of using a NAND chip for the SSD of the base version of the MacBook Air, which ended up halving the read and write speeds, and this year all models with 2 sells NAND chips; The maximum speed of 4 and 3.5 GB/s for reading and writing is lower than Windows competitors; But it’s not bad either.

There is a lot of debate on social networks about whether 8GB of RAM is sufficient or not. A number of Apple fans, with the logic that “MacBook RAM has high speed and memory swap technology is available to help SSD as RAM”, say that in many applications, 8 GB of RAM is enough; But you should pay attention to several points:
1. The data is not just traveling between the chip and RAM, which can compensate for the low capacity of the RAM by just having a high data exchange rate; In some applications, such as modeling or graphic work, several gigabytes of data may be stored in RAM for a relatively long time. Let’s say that the data exchange rate between the RAM and the M3 or M2 chip is no longer the best, and some chips such as the Core Ultra 7 155H offer a higher rate.
2. Memory swap is not a magical and new technology; The rest of the operating systems, such as Windows, also have similar technology; But it should be noted that swap memory reduces the useful life of SSD and the speed of SSD is not at the level of RAM that can fully play its role; For example, in MacBook Air M3, the data exchange rate between RAM and chip also reaches 102 GB/s; While the Mac SSD read and write rate is maybe one twentieth of this number.
3. Software tools are constantly developing, and their need for hardware resources, including RAM, also increases day by day. On the other hand, the user also buys the MacBook for a few years of use; Therefore, due to the lack of ability to upgrade RAM, one may face problems over time.
Aside from all the talk about Rome, a number of domestic sellers are also taking advantage of the opportunity; For example, Apple charges the same amount for a MacBook Air with 16 GB of RAM and 256 GB of SSD as for an 8 | 512 GB considered; But in Iran, configuring MacBook with more RAM is much more expensive than configuring with more SSD.
MacBook Air M3; Attractive and not very valuable
The MacBook Air M3 is by no means a bad product; But what makes buying this ultrabook illogical is the great value of its predecessors, especially the MacBook Air M1, especially if we consider their significant price difference.
For a person who does not have a laptop and is looking for a compact and well-made ultrabook for daily and light use, the base model of MacBook Air M1, which is currently sold at a price of 47-48 million Tomans, is a very desirable option; A device with an integrated metal body, a high-quality display, a very good keyboard and trackpad, excellent charging and fast performance that meets all the needs of an individual with daily use, journalism or light content production; Without the need to take an irrational action, about 25 million Tomans more will be spent to buy M3.
A person who already has a MacBook Air M2 and uses it for daily use should not go for the MacBook Air M3; Because it will not experience any significant changes; Except for the faster SSD, which is hardly noticeable in everyday use. For a current Mac M1 user, it might make more sense to upgrade to the M3.
For people who use laptops for tasks such as programming or video editing, the 8GB version of the MacBook Air M3 is not really a rational choice. If these people prefer macOS, it is better to go for used models with a budget of 70-75 million tomans, such as M1 Pro with 16 GB RAM, or if they are comfortable with Windows, high-quality options such as HP Envy with Core i9-13900H processor. And 16 GB of RAM will be a reasonable option for them.

The strangest things that can happen to humans in space
When it comes to space and astronautics, we all remember very interesting movies in which strange things happen to astronauts. Movies with exciting stories, most of which are nothing but the authors’ imaginations; But there are other very amazing stories happening in space that are completely real and have nothing to do with human imagination. In this article, we try to discuss some examples of these events and introduce you to the wonders of space travel.
Strange things that happen to humans in space
The human heart changes shape in space
It may seem a bit strange and even unbelievable that traveling to space can change the shape of the heart, But such a thing happens in reality and scientific studies have proven it. Less work of the heart and less pumping of blood leads to a decrease in the volume of the muscles of this organ, and this ultimately causes the hearts of astronauts to become more spherical by about 9.4%.
Despite the temporary nature of these conditions, some doctors believe that the reduction in the volume of the human heart during space travel may have serious consequences. According to NASA, researchers are researching this issue, and the results of this study will not only help astronauts but will also affect ordinary people and the inhabitants of the planet.
There is a possibility of mental problems in space
Living in the extraterrestrial atmosphere is associated with many problems. Changing living conditions and experiencing a completely different environment with very specific conditions imposes many psychological pressures on astronauts. These issues cause astronauts to experience special psychological conditions and are susceptible to various problems such as anxiety and depression.
Being away from family, lack of simple facilities such as sunlight or even fresh food, and heavy work are among the reasons that expose astronauts to various mental illnesses.
Human vision decreases in space
Visual impairment caused by intracranial pressure or VIIP is another space travel wonder faced by astronauts. This problem was observed for the first time in 2005 and in an astronaut named John Phillips. The Washington Post investigates this issue in an article and states that Phillips experienced a significant loss of vision after returning from his space trip. This incident prepared the groundwork for the researchers’ research for further investigations.
Additional research showed the changes in the appearance of the astronauts’ eyes and the loss of their vision after returning from space travel. Currently, the only possible reason that has been proposed for the occurrence of such conditions is the lack of gravity and the creating double pressure on the astronauts’ skulls; Of course, the research in this field continues and it is still not possible to say with certainty a specific reason for the occurrence of these conditions.
The body’s immune system weakens in space
Traveling to space, along with its excitement and surprises, also brings many problems for humans. One of these problems is the weakening of the body’s immune system in space, which was first discovered by astronauts during the Apollo mission. The story was that the astronauts in this mission experienced problems such as irregular heartbeat, dehydration, and inner ear disorder, and faced many problems after returning from the mission.
Studies conducted in this field have shown that after leaving the Earth’s atmosphere, the immune system of astronauts weakens, in part due to the abnormal activation of a type of immune cells called T-regulatory lymphocytes. This weakening is sometimes so severe that it causes astronauts to deal with latent viruses such as chicken pox in addition to simple infectious diseases such as colds after returning from space travel.
Astronauts can lose their fingernails
As you know, astronauts wear special clothes to carry out their missions in space, which includes astronaut gloves. These gloves are designed in such a way that they put a lot of pressure on the astronauts’ hands and nails; This will eventually lead to their nails falling off.
It is true that the fall of fingernails or their swelling is not a simple matter that can be easily passed over, But it seems that doing more research to design more suitable gloves can minimize the possibility of this problem and astronauts will not face such a problem in the future.
Human height grows taller in space
Another wonder of space travel, which makes it one of the favorite trips of ordinary people, is the increase in height that occurs during this trip. As soon as you leave the Earth’s atmosphere, the gravity is close to zero, and this causes the pressure on the spine to decrease significantly. The reduction of this pressure, in turn, causes the height of the astronauts to grow a few centimeters.
One of the studies that confirms the truth of this issue is the research that NASA scientists conducted on two twin brothers. In this study, one of the twins had a 342-day trip to space and the other brother was examined on Earth. The results of this and other research determined that the height of astronauts increases by 2 to 5 cm on average after space travel.
Mark Kelly (left) and Scott Kelly (right) made it possible for researchers to study the health effects of long-duration space travel by studying NASA twins.
Traveling to space leads to weakening of muscles
Another strange thing that happens to astronauts in space and affects their health is the weakening of muscles or atrophy. Long space travel causes muscle wasting in astronauts, so they are trained to exercise continuously during their journey.
NASA is working on this issue to find solutions to prevent the problem of muscle wasting. The reason for the importance of this issue is the need for astronauts to have strong muscles and a healthy body so that they can perform their difficult missions in space in the best possible way.
Space swells astronauts’ faces
A large volume of our body is made up of liquid. On Earth, gravity pulls this fluid down and collects some of it in the lower limbs; But in space, where microgravity prevails, our body fluids are more evenly distributed; As a result, astronauts’ faces look puffier than normal, and on the other hand, their legs appear thinner than when they are on Earth.
According to the Washington Post, “the phenomenon of puffy-faced bird’s legs” appears when blood and other body fluids accumulate on the side of the upper body due to low gravity and stay there; As a result, the heads swell and the legs shrink. In this situation, the appearance of the astronauts can change by swelling their faces. Astronauts may experience excessive blood pooling; As if their head is constantly cold. However, after a few weeks in space, your body will adjust to the change in gravity and some of the facial puff will fall asleep.
Space travel may increase the risk of cancer
Astronauts who spend 6 months in space are exposed to almost as much radiation as a thousand chest X-rays. Exposure to different types of radiation exposes the body to the risk of cancer, damage to the central nervous system, bone loss, and some cardiovascular diseases. However, it has been difficult to accurately calculate the level of risk so far. Also, scientists’ information about the impact of radiation in long-duration space missions to deep space destinations such as the Moon and Mars is still limited.
The more time a person spends in space, the more radiation they are exposed to and, theoretically, the more DNA damage they accumulate. It is not possible to say with certainty whether this DNA damage actually increases the risk of cancer; Because cancer is affected by many environmental and genetic factors. For example, it’s probably fair to say that today’s astronauts are probably some of the fittest people on the planet.
