Apple in November released the first Macs with an Arm-based M1 chip, debuting new 2020 13-inch MacBook Pro, MacBook Air, and Mac mini models. The M1 chip has received rave reviews for its incredible performance and efficiency, and it is the culmination of more than a decade of Apple's work on chips created for the iPhone and the iPad.

This guide walks through everything that you need to know about the M1 chip and how it's different from the Intel chips that came before it.

Apple's M1 Chip Explained

The M1 is the first Apple-designed System on a Chip (SoC) that's been developed for use in Macs. It marks Apple's transition away from the Intel chips that the Cupertino company has been using in Macs since 2006.

As a "System on a Chip," the M1 integrates several different components, including the CPU, GPU, unified memory architecture (RAM), Neural Engine, Secure Enclave, SSD controller, image signal processor, encode/decode engines, Thunderbolt controller with USB 4 support, and more, all of which power the different features in the Mac.

Prior to now, Macs have used multiple chips for CPU, I/O, and security, but Apple's effort to integrate these chips is the reason why the M1 is so much faster and more efficient than prior Intel chips. The unified memory architecture that Apple has included is also a major factor because all of the technologies in the M1 are able to access the same data without having to swap between multiple pools of memory.

m1 chip unified memory architecture speed
Built into the M1 chip, the unified memory architecture lets the CPU, GPU, and other processor components don't need to copy data between one another, and are able to access the same data pool. This brings notable speed and efficiency improvements to the M1. This memory architecture means that the RAM is not user upgradeable, which isn't too much of a surprise because few Macs have user accessible RAM. M1 Macs max out at 16GB RAM, but even the base 8GB is enough for everyday tasks.

There are 16 billion transistors on the M1, which is the most Apple has ever put into a chip for the fastest CPU core available in low-power silicon and unparalleled CPU performance per watt. Apple's chip design has allowed it to create Macs that are faster and more power-efficient than was possible with Intel-designed chips, and further enhancements are available through the new tighter integration of an Apple-designed chip paired with Apple-designed software.

What's Different About the M1

Unlike Intel chips built on the x86 architecture, the Apple Silicon M1 uses an Arm-based architecture much like the A-series chips that Apple has been designing for iPhones and iPads for years now.

The M1 chip is the most powerful chip that Apple has created to date, and it is similar to the A14 chip in the latest ‌iPhone‌ and iPad Air models, built on a 5-nanometer process by Taiwan Semiconductor Manufacturing Company (TSMC). TSMC builds all of Apple's chips and has done so for many years.

Macs With M1 Chip

Apple has released the 2020 ‌MacBook Air‌, 13-inch MacBook Pro, and ‌Mac mini‌ with M1 chips, replacing the low-end machines in those lineups. The M1 ‌MacBook Air‌ is now the only ‌MacBook Air‌ that Apple sells, but there are still Intel ‌Mac mini‌ and MacBook Pro models available.

apple m1 macs trio
It is not worth purchasing an Intel ‌Mac mini‌ or 13-inch ‌MacBook Air‌ at this point because the M1 chip outperforms all of the chips used in Apple's portable devices and it is only outclassed by desktop processors.

CPU, GPU, and Neural Engine

CPU

The M1 chip includes an 8-core CPU with four high-performance cores and four high-efficiency cores. The high-performance cores are designed to offer the best performance for power-intensive single-threaded tasks.

The four high-performance cores can work together to offer impressive multithreaded performance that has allowed the M1 Macs to outshine even the highest-end 16-inch MacBook Pro models.


For tasks that are less intensive and don't require the same power, such as web browsing, there are four high-efficiency cores that use a tenth of the power to preserve battery life.

Apple says these cores offer performance similar to the prior-generation dual-core ‌MacBook Air‌, but at much lower power. These cores can work alone when significant power isn't needed, but for demanding tasks, all eight cores can be engaged at one time.

Benchmarks of the ‌MacBook Air‌, MacBook Pro, and ‌Mac mini‌ have confirmed the M1 chip's impressive performance. There are some thermal differences between the models, but all have the highest single-core performance out of any Mac and multi-core performance on par with Apple's desktops.

m1 macs geekbench score charts
The highest-performing Mac of the bunch, the ‌Mac mini‌, earned a single-core Geekbench 5 score of 1702 and a multi-core score of 7380, with the ‌MacBook Air‌ and MacBook Pro coming in just behind.

GPU

The ‌Apple Silicon‌ chip has an 8-core GPU, but there's also a version used in the entry-level ‌MacBook Air‌ models that has one of the cores disabled for a 7-core GPU.

GPUs in the ‌Mac mini‌, MacBook Pro, and higher-end M1 ‌MacBook Air‌ models are all 8-core GPUs capable of running close to 25,000 threads simultaneously and with 2.6 teraflops of throughput. According to Apple, the M1 has the fastest integrated graphics in a personal computer.

m1 mac gpu benchmark
Graphics performance tests have suggested the M1 chip offers performance that exceeds the GeForce GTX 1050 Ti and Radeon RX 560. It also earned an OpenCL score of 19305, similar to the Radeon RX 560X and Radeon Pro WX 4100.

Neural Engine

The M1 chip has a built-in Neural Engine, a component that Apple first started adding to its A-series chips a few years ago. The Neural Engine is designed to accelerate machine learning tasks across the Mac for things like video analysis, voice recognition, image processing, and more.

The 16-core Neural Engine is capable of 11 trillion operations per second for up to 15x faster machine learning performance compared to the previous generation of models that have moved to the M1.

Apple M1 Speed

The M1 chip brings up to 3.5x faster CPU performance, up to 6x faster GPU performance, and up to 15x faster machine learning capabilities compared to the Intel chips used in prior-generation machines.

Compared to the latest PC laptop chips, the M1 offers 2x faster CPU performance and does so using just 25 percent of the power.

Battery Life

Even with the incredible speed improvements that the M1 chip brings, it is also more battery-efficient than any other Mac chip Apple has released to date.

Battery life in an M1 Mac lasts up to 2x longer than in prior-generation Macs. The Mac with the longest battery life is the 13-inch MacBook Pro, which lasts for up to 20 hours. That's double the battery life of the prior-generation model.

Intel Comparisons

Apple used the M1 chip in lower-end Macs, and when it comes to CPU performance, the M1 beats out even the highest-end chips used in Intel Apple's notebook lineup. The M1 chip has the fastest single-core performance of any Mac, and the multi-core performance isn't too far off from many of Apple's desktop machines.

Apple is still selling Intel 13-inch MacBook Pro and ‌Mac mini‌ models, and performance-wise, the M1 versions of these Macs offer much faster CPU speeds. It's not a good idea to buy a non-M1 version of the 13-inch MacBook Pro or ‌Mac mini‌ at this time because of the inferior performance unless compatibility with x86 apps and the option to run Windows is a concern.

Other Macs in Apple's lineup will be transitioning to ‌Apple Silicon‌ chips in the future, which is something to keep in mind when considering a purchase. At this time, Apple's higher-end notebooks and desktops still offer superior GPU performance, but that could change in the future when new versions of ‌Apple Silicon‌ chips debut.

M1 Security Features

Intel Macs had a built-in T2 chip that handled security and other features on the Macs, but with the M1 chips, that functionality is built right in and a secondary chip isn't required.

The M1 has a built-in Secure Enclave that manages Touch ID and a storage controller with AES encryption hardware for SSD performance that's faster and more secure.

Running Apps on M1 Macs

Because the M1 chip is using different architecture, Apple has built tools to allow developers to create Universal app binaries that run flawlessly on both ‌Apple Silicon‌ and Intel chips, plus it has developed the Rosetta 2 translation layer that allows x86 apps to run on the M1 chip.

rosetta 2
Rosetta 2 is a reimagining of Rosetta, the feature that allowed PowerPC apps to run on Intel-based Macs back in 2006 when Apple swapped to Intel from PowerPC.

With Rosetta 2, apps designed for Intel machines will continue to run on M1 Macs with some limited performance compromises. For the most part, apps will run similarly on both Intel and M1 Macs due to the performance improvements introduced in the M1.

Everything should function as normal when transitioning to M1 Macs, and over the course of a few years, most popular Mac apps will likely be built to run on the M1 Macs natively. Right now, there is one major compromise when choosing an M1 Mac, and that's Windows support.

There is no Boot Camp for M1 Macs and M1 Macs are not officially able to run Windows, although some users are figuring out ways to make it work. Official support could come in the future, but it largely depends on Microsoft licensing its Arm-based version of Windows to consumers, and so far, that hasn't happened.

M1 Macs can run ‌iPhone‌ and ‌iPad‌ apps as well as Mac apps, so long as app developers make them available on the Mac. There used to be a way to sideload any iOS app on an M1 Mac, but that functionality was removed in January 2021.

M1 Mac How Tos

Since the M1 Macs are using a new type of chip designed by Apple, there are some tips and tricks for doing things like transferring files, entering recovery mode, and finding apps optimized for the new machines. We have several M1-specific how tos that are worth checking out.

The Future of Apple Silicon

Apple is planning to transition the entire Mac lineup to ‌Apple Silicon‌ chips, doing away with Intel chips entirely. Apple expects the process of moving its entire product line to ‌Apple Silicon‌ to take right around two years.

The next Macs that could get ‌Apple Silicon‌ chips include the iMac, with a 24-inch version rumored to be in the works, and redesigned 16.1-inch and 14.1-inch MacBook Pro models.
