We’re creeping up on the five-year anniversary of Tim Cook dinner’s Apple Silicon announcement, and over a decade of rumors. Here is how the entire saga began, the way it launched, and what to anticipate sooner or later.
After years of coping with Intel’s chip limitations, Apple launched the transfer to Apple Silicon throughout WWDC 2020. The trouble of ditching a well-used structure would see Apple shifting to its new line of designed in-house chips for its Mac and MacBook catalog, beginning later that very same yr.
That two-year transition from Intel to Apple Silicon began a significant change for the corporate, in addition to the {industry} at giant. Past claims of excessive effectivity designs paired with excessive ranges of efficiency, which you’d count on from a chip launch.
Apple Silicon additionally launched essentially the most forward-looking function of its iPhone chips to desktop. The addition of the Neural Engine in its M-series chips was groundbreaking, and compelled the remainder of the computing {industry} to think about shifting in comparable methods with their very own processor decisions.

The chip essentially adopted the essential thought of a processor with a built-in GPU, which was and nonetheless is a reasonably typical idea in processing. The Neural Engine definitely added extra efficiency in duties that would profit from machine studying, however one other change from the norm additionally helped.
Moderately than utilizing discrete reminiscence swimming pools for the CPU and GPU, in addition to different elements, Apple determined to make use of Unified Reminiscence. This went in opposition to the same old idea through the use of a single giant pool of reminiscence that the entire CPU parts might entry.
The thought helped efficiency in a number of methods, together with permitting the elements to entry the identical knowledge in reminiscence with out needlessly duplicating it.
There’s additionally the profit to the GPU in that the extra Unified Reminiscence was included, the extra reminiscence it had entry to for graphical work. This allowed the GPU in Apple Silicon to have entry to much more reminiscence than you can discover in trendy discrete GPUs or graphics playing cards for PCs.
Whereas the introduction of Apple Silicon on the time targeted on the M1 and M-series chips destined for Mac utilization, the time period has expanded in its use. It now refers to all of Apple’s principal processing chips, together with its A-series used within the iPhone and iPad strains, which have been additionally the forerunners for the M-series vary.
Apple Silicon is in every single place, it is not simply processors, and it is not simply within the Mac. However, to maintain issues easy this time round, we will probably be discussing Apple Silicon from the unique Mac-centric viewpoint.
However even simply taking the M-Collection by itself, the progress Apple Silicon has made since its introduction has been staggering, and industry-challenging.
Pre-Apple Silicon: Bother with Intel
Apple’s resolution to make its personal chips was pushed by appreciable points the corporate had with Intel.
Within the 2010s, Intel was a significant computing pressure. It was a standing it had earned for years, nevertheless it wasn’t one thing the chip maker might preserve.
Maintaining with Moore’s Regulation was extraordinarily arduous for Intel to proceed, as a result of fixed die shrinks it required. Every new course of enchancment added new obstacles, whereas subsequent die shrinks continued to be tougher to excellent.
Finally, Intel dismissed its well-known Tick-Tock cadence of a course of change (Tick) was adopted by an structure replace inside that course of (Tock). As a substitute, by 2016, Intel had switched to a Tick-Tock-Tock technique, tacking an optimization part on the tip to get extra out of a course of earlier than shrinking to the following one.
Inevitably, the delays on die shrinks, such because the introduction of 10-nanometer Intel chips, was an excessive amount of for Apple to take care of.
This was solely one of many points Apple confronted with Intel, with the warmth generated from chips and excessive energy consumption being huge issues that solely grew greater. In 2018, it resulted in thermal throttling points affecting that yr’s MacBook Professional updates.
The throttling was extreme sufficient to be a difficulty, and exacerbated by dangerous firmware. Shoppers rapidly caught on.
Following our personal testing, AppleInsider’s Mike Wuerthele mentioned the throttling at size on Leo LaPorte’s The New Display screen Savers.
Notably, Mike mentioned that what would finally be known as Apple Silicon would debut in 2020 on the low finish of Mac {hardware}.
There have been rumors going again years earlier than that Apple was bringing extra of its cell chip work internally, together with some going as far again as 2011. A transfer over to Mac chip growth was seemingly inevitable as Apple’s expertise continued to develop.
Definitely, it had limitations to traverse to get there, however over time, it had the data and functionality to go its personal method from Intel.
Plainly Intel’s faltering relationship with Apple gave the iPhone maker extra of an incentive to make the bounce to Macs.
It had already mastered managing the thermal and energy wants for its personal chips to increase iPhone battery life and maintain the smartphones from overheating. It made sense that its data may very well be used on desktop-class processors to nice impact.
Working with long-time chip associate TSMC, that is exactly what Apple did.
M1: The unique releases
The primary Apple Silicon {hardware} Apple launched after Tim Cook dinner’s announcement wasn’t one with an M1 chip. Actually, it was an A-series chip.
The Developer Transition Equipment was handed out as a personalized Mac mini, gutted of Intel elements and as an alternative full of Apple Silicon {hardware}. The middle of that was the Apple A12Z Bionic, which is an apt selection because the most-powerful A-series chip, and similar to what builders might count on from the primary official ARM-based launch.
The completely different sizes of M1-series chips – Picture credit score: Apple
The M1 sequence began off with the M1, made utilizing a 5-nanometer course of. It had 16 billion transistors, 4 high-performance cores and 4 energy-efficient cores, and a seven or eight-core GPU.
As for the Neural Engine, it was a 16-core part able to 11 trillion operations per second. Whereas the reminiscence portions have been low at 8GB or 16GB, additionally they labored with 68.25GB/s of reminiscence bandwidth, glacial in comparison with trendy variations.
It took virtually a yr for Apple to ship M1 Professional and M1 Max chips, which introduced extra energy and efficiency.
The Professional had both six or eight efficiency cores within the CPU together with two effectivity cores. The Max model had eight efficiency cores and 4 effectivity cores.
The GPUs on every additionally noticed core depend will increase, of 14 to 16 on the Professional and 24 to 32 on the Max. The Neural Engine stayed the identical, however the reminiscence bandwidth shot as much as 200GB/s and 400GB/s respectively.
One other addition that the M1 chip missed out on fully was the Media Engine, or devoted {hardware} for decoding and encoding video. This function made the M1 Professional and later chips improbable for video editors and content material creatives, particularly these engaged on the {industry} commonplace ProRES.
A really late arrival in March 2022 was the M1 Extremely, one other groundbreaking chip otherwise. Utilizing an interconnect, Apple successfully welded two M1 Max chips collectively, creating one thing that was twice as {powerful} in virtually all respects.
That meant as much as 16 efficiency cores on the CPU together with eight effectivity cores, a GPU core depend of as much as 64 cores, and a 32-core Neural Engine. Because it’s two chips hooked up collectively, it made sense that it had two of every thing the Max provided.
As the road and core counts grew, you can additionally see a rise in efficiency. The capabilities of every core did not improve, however the sum complete was much more helpful to finish customers.
Utilizing the newest Geekbench outcomes, it is simple to see this development in efficiency. For comparability functions, we’re utilizing the highest rating for every chip, no matter core counts or mannequin.
Single-core benchmarks – M1
The one-core check had all 4 across the similar kind of stage, under or round 2,400 factors. This is smart, because the check makes use of just one quick core, and so they’re fairly similar throughout the board for the era.
Multi-core benchmarks – M1
The multi-core benchmarks begin to present some differentiation, and that is primarily as a result of sheer variety of cores at play for every. The extra cores to make use of, the upper the rating.
Metallic benchmarks – M1
This can be a lot extra evident with the Metallic benchmarks, since they depend on GPU core counts. There are appreciable jumps between every chip tier right here.
M2: The following era
Launched in June 2022, the M2 sequence began off in an analogous method because the M1, with the introduction of the base-tier chip. Once more, a 5-nanometer course of was used, however Apple elevated the transistor depend to twenty billion from the 16 billion of the M1.
The bottom M2 chip’s stats – Picture credit score: Apple
The CPU continued to have a four-performance, four-efficiency core cut up, however with the cores providing efficiency enhancements over the earlier era. The GPU additionally benefited with choices as much as 10 cores in complete.
The Neural Engine was beefier, with its 16 cores able to 15.8 trillion operations per second. Reminiscence bandwidth was additionally elevated to a spherical 100GB/s.
Following its established playbook, the M2 Professional and M2 Max arrived in January 2023. Once more, there have been extra cores to play with, because the M2 Professional had six or eight efficiency cores and 4 effectivity cores, whereas the Max had eight efficiency and 4 effectivity cores.
The GPU choices additionally scaled up, with 16 to 19 on the Professional and 30 to 38 cores on the Professional Max. The identical stage of reminiscence bandwidth upgrades for his or her respective tiers have been current once more.
It took till June for Apple to deliver out the M2 Extremely. As soon as once more fusing two M2 Max chips collectively, it had 16 efficiency cores, eight effectivity cores, a 32-core Neural Engine, as much as 76 GPU cores, and used 134 billion transistors.
The reminiscence allowance was additionally phenomenal, with it in a position to make use of as much as 192GB. All benefiting from as much as 800GB/s of reminiscence bandwidth.
Single-core benchmarks – M2
On a efficiency foundation, the single-core efficiency was higher total, however with little differentiation as soon as once more. The multi-core rating exhibits much more, with the M2 Professional and M2 Max being pretty shut within the center.
Multi-core benchmarks – M2
As soon as extra, the GPU facet exhibits the M2 Extremely as being massively performative. This made it a favourite for visible creators for fairly a while.
Metallic benchmarks – M2
M3: The tough third album
By the third era, the tech media was used to how Apple launched its new Apple Silicon releases. Or a minimum of it thought it understood the cadence of releases.
The October 2023 introduction of M3 was very uncommon, mainly as a result of Apple did not simply introduce one M3 chip. It introduced out the Professional and Max variations on the similar time.
Apple launched three M3 chips on the similar time
With using a brand new 3-nanometer course of, and 25 billion transistors, the M3 provided a really acquainted make-up for customers. There was the eight-core CPU with 4 efficiency and 4 effectivity cores, identical to final time, and a 10-core GPU on the high finish as soon as once more.
Whereas seemingly comparable at this level, there have been variations. Apple itself insisted that the CPU and GPU enhancements have been 35% and 65% higher respectively versus the M1 chip.
The Neural Engine additionally gained some efficiency, with the 16-core part upgraded to run at as much as 18 trillion operations per second.
One huge change this time was a expertise known as Dynamic Caching, which allowed the GPU to allocate using native reminiscence in {hardware} in actual time. This meant it might allocate solely the quantity of reminiscence it wanted, rising utilization.
The GPU additionally gained hardware-accelerated ray tracing and mesh shading. This helped produce visually complicated scenes in video games and different graphical purposes.
The M3 Professional and M3 Max did differ fairly a bit from the norm, as Apple differentiated the CPUs greater than regular. The Professional had an 11-core or 12-core CPU, with both 5 – 6 efficiency cores paired with six effectivity cores.
Single-core benchmarks – M2
The M3 Max had both 10 or 12 efficiency cores, together with 4 effectivity cores. In addition to having extra cores than the Professional, the M3 Max had fewer effectivity cores to take care of.
Reminiscence bandwidth was a little bit of a step again for this era. The 150GB/s and 300GB/s charges this time round have been decrease than their M2 counterparts.
When it got here to the GPU, the M3 Professional had 14 to 18 cores, whereas the M3 Max had 30 to 40 GPU cores.
Multi-core benchmarks – M3
The M3 Extremely was much more of a thriller, because it did not arrive in a well timed method. Rumor mill hypothesis questioned whether or not the chip was killed off in favor of a faster shift to the M4 era.
It did finally flip up, although, in March 2025. This was months after the discharge of the M4 Professional and Max, the following era alongside.
Metallic benchmarks – M3
Simply as ordinary, the M3 Extremely is made by sticking two M3 Max chips collectively as one. This meant CPU core counts of 28 or 32 cores, with both 20 or 24 efficiency cores paired with eight effectivity cores.
A 32-core Neural Engine was additionally included, in addition to a 60 or 80-core GPU. The reminiscence capability jumped as much as 512GB of unified reminiscence and provided 800GB/s of reminiscence bandwidth.
On the subject of the efficiency graphs, the principle factor to have a look at is the multi-core outcomes. Not like the M2 and M3 generations, you may see a substantial separation between the M3 Professional and M3 Max chips.
M4: A continuation of development
The M4 is the present era of Apple Silicon for Mac, and the best efficiency of the gathering.
Launched in Might 2024, the M4 used a three-nanometer course of and squeezed in 28 billion transistors. It was a 9 or ten-core CPU, with both three or 4 efficiency cores combined with six effectivity cores.
The M4 included six effectivity cores this time round – Picture Credit score: Apple
There was a ten-core GPU with the identical upgrades because the M3 model and a 16-core Neural Engine able to 38 trillion operations per second. Reminiscence bandwidth improved to 120GB/s.
The M4 Professional pushes the specs to both a 12-core or 14-core CPU with eight or ten efficiency cores and 4 effectivity cores, as if Apple discovered its lesson from the M3 Professional. The M4 Professional GPU was accessible in 16-core and 20-core varieties, with reminiscence bandwidth as much as 273GB/s.
Single-core benchmarks – M4
The M4 Professional additionally improved on the M4 by upgrading its Thunderbolt help, from Thunderbolt 4 to Thunderbolt 5. This meant extra bandwidth for knowledge transfers between units, at 80Gbps versus 40Gbps.
The M4 Max went even additional than the M4 Max, with a selection of 14-core or 16-core CPUs with 10 or 12 efficiency cores and 4 effectivity cores. The GPU rose to a 32-core or 40-core model, and reminiscence bandwidth went as much as 546 GB/s.
Multi-core benchmarks – M4
On the time of reporting, there is not an M4 Extremely, and one is not anticipated. Apple itself says that not each Apple Silicon era may have an Extremely chip, so there aren’t any ensures one will probably be on the best way.
On a efficiency foundation, the single-core outcomes are once more pretty even, with the Max being barely above the remainder.
Metallic benchmarks – M4
The multi-core check is, once more, displaying a development in efficiency that is pushed by core counts. Although this time, the distinction between Professional and Max is barely much less pronounced than the M3.
Unsurprisingly, the Metallic outcomes present the identical kind of core count-based consequence. The extra cores, the upper the consequence.
From M1 to M4
Apple has demonstrated that it has improved Apple Silicon because the generations handed. Newer variations noticed advantages over the older model in virtually all instances, with a couple of inter-generational wobbles.
The principle adjustments through the years have been core speeds and core counts. That’s handily demonstrated by evaluating the entire single-core ends in one chart.
All M-series benchmark scores for single-core testing below Geekbench
You’ll be able to see an enchancment of 60% between the bottom M1 and M4 chips, rising to 62% for the M1 Max and M4 Max. Certainly, you may see fairly neat intergenerational jumps between the variations.
While you flip to the multi-core scores, it is apparent that clock pace is just one issue. Core depend will increase can even enlarge the variations.
All M-series benchmark scores for multi-core testing below Geekbench
The bottom M4 is 74% sooner than the M1 equal, however higher tiers see extra development. By the point you evaluate the M1 Max and M4 Max, the advance rises to 203%.
Turning to graphical efficiency below Metallic, the most important positive aspects occur to be with the bottom variations. There is a 74% distinction in Geekbench Metallic scores between the M1 and M4 chips.
All M-series benchmark scores for Metallic testing below Geekbench
That is to not say the others are lesser, because the Professional and Max see 65% and 62% equivalents in a three-generation distinction. Even the two-generation bounce from the M1 to M3 Extremely is a 61% enchancment.
One factor that could be very obvious wanting on the charts collectively is that the upgrades are pretty constant throughout the generations. There’s roughly the identical stage of enchancment every time, which bodes properly for the longer term.
The following 5 years
If Apple’s something, it is each punctual and a creature of behavior. That’s to say, what will probably be arriving within the subsequent few years for Apple Silicon needs to be extra of the identical.
Quasi-annual enhancements throughout the board, and the identical kind of generational construction because it has now. Spotty additions of Extremely chips apart.

The M5 era is anticipated to be arriving quickly, with it allegedly already in mass manufacturing. As for what the brand new factor may very well be this time, it has been speculated that Apple will shift to separate the CPU and GPU, which might additional enhance efficiency.
There’s even been claims concerning the M6 taking onboard Apple’s modem tech into an all-in-one answer for cell units. Suppose mobile connectivity on a MacBook Professional with no need to tether to an iPhone.
Whereas we do not know what the longer term will exactly maintain for Apple Silicon, we will confidently say that it’ll nonetheless be getting higher as time rolls on.
