When Apple launched the M1 chip on the finish of 2020, we had been blown away by the pace enhancements over its Intel predecessors. A yr later Apple did it once more with the M1 Professional and M1 Max, after which in March 2022, Apple revealed the M1 Extremely, filling out the M1 chip lineup and dramatically altering our expectations for Apple’s roadmap. Right here’s how the Apple silicon transition has gone to this point—and the place it’s going.
M1: December 2020
Apple’s present M1 processor relies on the 5nm A14 chip that first arrived within the iPad Air (4th era) and iPhone 12. It has 4 high-performance cores with 192 KB of L1 instruction cache and 128 KB of L1 information cache and shared 12 MB L2 cache and 4 energy-efficient cores with 128 KB of instruction cache, 64 KB of L1 information cache, and shared 4 MB L2 cache. That makes a complete of eight cores break up evenly amongst energy and effectivity resulting in super pace boosts over the prior fashions. The system-on-a-chip additionally has an eight-core GPU in most fashions (the entry-level MacBook Air and 24-inch iMac have a 7-core GPU) with 128 execution models and as much as 24576 concurrent threads.

Reminiscence has additionally modified. With the M1, the LP-DDR4 reminiscence isn’t simply soldered to the motherboard, it’s really a part of the chip itself. Meaning it’s quicker and extra environment friendly than earlier than, but it surely’s additionally a bit extra restricted—you may solely get 8GB or 16GB in an M1 Mac and there’s no option to improve it after buy. (That gained’t be a shock for MacBook patrons however the identical additionally applies to desktop fashions, although we’re undecided concerning the Mac Professional but.) And at last, the chip has a 16-core Neural Engine, together with the Safe Enclave and USB4/Thunderbolt help.
M1 Professional and M1 Max: October 2021
We began listening to concerning the growth of an M1X chip earlier this yr, however the rumors weren’t fairly correct. Apple is asking its next-gen processors the M1 Professional and M1 Max, and true to their names, they’re an enormous leap over the M1.
Constructed utilizing the identical 5nm course of because the M1, the M1 Professional and M1 Max carry a brand new 10-core CPU, together with eight high-performance cores and two high-efficiency cores, that delivers speeds as much as 70 % quicker than the M1. The M1 Professional provides as much as 200GB/s of reminiscence bandwidth with help for as much as 32GB of unified reminiscence whereas the M1 Max delivers as much as 400GB/s of reminiscence bandwidth with help for as much as 64GB of unified reminiscence.
On the graphics facet, the M1 Professional has a 14-core or 16-core GPU that’s as much as 2x quicker than M1, whereas the M1 Max provides a 32-core GPU choices for as much as 4x quicker graphics efficiency than M1. In keeping with Apple, the brand new M1 Max MacBook Professional can transcode ProRes video in Compressor as much as 10x quicker in contrast with the Intel 16-inch MacBook Professional.
Moreover, the chips even have a 16-core Neural Engine, further Thunderbolt 4 controllers, and a brand new show engine that may drive as much as 4 exterior shows on the M1 Max. You will discover them within the 14- and 16-inch MacBook Professional.
M1 Extremely: March 2022
The M1 Extremely got here as a shock throughout Apple’s “Peek Performance” occasion in March. Apple did job conserving this processor underneath wraps—the rumors that popped up concerning the Mac Studio a few days earlier than the occasion merely described the Extremely as a variant of the M1 Max.
Seems that calling the M1 Extremely a variant is deceptive—it’s really two Max chips that work collectively as one. Apple created a particularly quick interconnect referred to as UltraFusion that gives 2.5TBps of bandwidth between the 2 dies, which permits the Extremely to be acknowledged as a single SoC by macOS.
Because the Extremely is 2 Maxes, you may double the specs of a single Max and also you get the lowdown on the Extremely. It has 20 CPU cores, with 16 efficiency cores and 4 effectivity cores, and a 48-core or 64-core GPU. The M1 Extremely is obtainable with 64 or 128GB of unified reminiscence, with a reminiscence bandwidth of 800GBps. And it has a 32-core Neural Engine.
The Extremely additionally has all of the media engines discovered within the Max, however once more, it has twice as many: two video decode engines, 4 video encode engines, and 4 ProRes encode and decode engines. Merely put, this is a perfect processor for video enhancing.
Mac Professional chip: Mid 2022
When John Ternnus introduced the M1 Extremely processor on the “Peek Performance” occasion, he declared it to be the final chip within the M1 household. Later within the presentation, he teased the ultimate Mac to transition to Apple silicon, the Mac Professional. Assuming each of these issues are true, Apple is engaged on a workstation-caliber desktop chip for the subsequent era of its Mac Professional tower that’s one thing totally different than a mere improve to the M1 Extremely. The Mac professional chip has been rumored to have as much as 40 cores attributable to a four-die course of or the pairing of chips with 32 efficiency cores, in addition to a 64-core or 128-core GPU.
Apple is reportedly creating a brand new Mac Professional with an extremely highly effective customized chip inside.
IDG
These numbers look lots like two M1 Extremely chips. So it’s attainable that Apple does one thing just like what it did with the M1 Max by ultrafusing two M1 Extremely chips right into a mega chip that brings these very rumored specs: 40 CPU cores (32 efficiency, eight effectivity), 128 GPU cores, 64 Neural Engine cores, and as much as 356GB of RAM. However now that the M1 Extremely has landed, it’s extra probably that Apple has one thing else up its sleeve for the Mac Professional, which has much more demanding energy and growth wants that the Mac Studio.
We don’t know if Apple will proceed to supply PCI slots for graphics and storage or just add extra ports for growth, however the Mac Professional is unquestionably probably the most fascinating Mac within the Apple silicon transition. We may get a peek on the machine at WWDC with a launch in November or December.
M2: Late 2022
There was an opportunity Apple may launch the M2 on the spring occasion, however we bought the M1 Extremely as a substitute. It nonetheless may arrive at WWDC, however extra probably it’s headed to fall, which places Apple silicon on a two-year cadence.
Apple’s M2 chip may debut in the subsequent MacBook Air, which seems to get an entire redesign with new colours to match the 24-inch iMac. In keeping with Bloomberg, Apple’s next-generation processor “will include the same number of computing cores as the M1 but run faster.” That’s just like how Apple approaches A-series upgrades, which has had six cores for the reason that A11 processor regardless of vastly improved efficiency. So far as the GPU goes, Bloomberg studies that the cores will enhance from seven or eight to 9 or 10. The M2 will probably be based mostly on TSMC’s N4P enhanced 5nm course of just like the A15 processor, in line with a report by The Info.
The colourful redesign of the MacBook AIr might be the primary M2 machine.
Based mostly on rumors and Apple’s positioning of its chips up to now, we will count on the M2 processor to be about 20 % quicker than the M1 however slower than the M1 Professional, M1 Max, and M1 Extremely. The identical M1 limitations on USB4/Thunderbolt and RAM will probably stay as effectively since Apple is establishing non-Professional and -Max chips as shopper merchandise for customers who aren’t as demanding.
M2 Professional and M2 Max: Mid-to-late 2023
The following era of Apple’s high-end laptop computer processors may have a number of tiers of efficiency just like the M1 Professional and M1 Max, with as many as 20 computing cores, made up of 16 high-performance and 4 high-efficiency cores, in line with a Bloomberg report. That’s attributable to a brand new distinctive two-die processor that can successfully double the cores in every chip, in line with a report in The Info. We count on these to launch in mid-to-late 2023, probably at WWDC or the autumn Mac occasion.
M3: 2024
Apple is already engaged on the third era of its M-series processor, in line with The Info. It would probably be its first desktop processor to make use of a 3nm course of and supply a major pace increase over the M1. Its code identify is Ibiza.
M3 Professional and M3 Max: 2025
We don’t know a lot concerning the M3 Professional and M3 Max aside from their codenames are reportedly Lobos and Palma, and the chip will probably be based mostly on a 3nm course of. Based mostly on the M1 timeline, this chip most likely gained’t arrive till 2025
