When Apple launched the M1 chip on the finish of final 12 months, we had been blown away by the velocity enhancements over its Intel predecessors. A 12 months later Apple did it once more with the M1 Professional and M1 Max and rumors counsel that the subsequent era will probably be an excellent larger leap. Right here’s how the Apple silicon transition has gone to date—and the place it’s going.
M1—December 2020
Apple’s present M1 processor relies on the 5nm A14 chip the primary arrived within the iPad Air and later the 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 8 cores cut up evenly amongst energy and effectivity resulting in large velocity boosts over the prior fashions. The system-on-a-chip additionally has an 8-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, however it’s additionally a bit extra restricted—you’ll be able to solely get 8GB or 16GB in an M1 Mac and there’s no strategy to improve it after buy. (That gained’t be a shock for MacBook consumers however the identical additionally applies to desktop fashions, although we’re no positive in regards to 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 in regards to the improvement of an M1X chip earlier this 12 months, 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 aspect, 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. Yow will discover them within the MacBook Professional and sure the upcoming 27- or 30-inch iMac.
M2—2022
Apple’s M2 chip will doubtless arrive in the subsequent MacBook Air, which appears to get an entire redesign with new colours to match the 24-inch iMac. In keeping with Bloomberg, Apple’s next-generation processor “will embrace the identical variety of computing cores because the M1 however run quicker.” 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, that the cores will enhance from seven or eight to 9 or 10. The M2 will doubtless be based mostly on TSMC N4P enhanced 5nm course of, in response to a report by The Info.
The colourful redesign of the MacBook AIr could possibly be the primary M2 machine.
We don’t know but how speeds examine, however based mostly on rumors and Apple’s positioning of its chips so far, we will anticipate the M2 processor to really be a bit slower than the M1 Professional. The identical M1 limitations on USB4/Thunderbolt and RAM will doubtless stay as properly since Apple is establishing non-X chips as shopper merchandise for customers who aren’t as demanding.
M2 Professional and M2 Max—Late 2022/Early 2023
The following era of Apple’s high-end processors might have a number of tiers of efficiency just like the M1 Professional and M1 Max, with 20 computing cores, made up of 16 high-performance or 32 high-performance cores and 4 or eight high-efficiency cores, in response to a Bloomberg report. That’s attributable to a brand new distinctive two-die processor the need successfully double the cores in every chips, in response to a report in The Info.
Apple is reportedly creating a brand new Mac Professional with an extremely highly effective customized chip inside.
IDG
Apple can also be engaged on a workstation-caliber desktop chip for the subsequent era of its Mac Professional tower that would additionally fall underneath the M2 Professional and M2 Max identify. It’s rumored to have as much as 40 cores attributable to a four-die course of or the pairing of chips, in addition to a 64-core or 128-core GPU, which might change the AMD GPUs in present fashions. These specs are similar to what Intel and AMD provide of their top-of-the-line workstation chips and would problem the quickest PCs.
We don’t know if Apple will proceed to supply PCI slots for graphics and storage or just add extra ports for enlargement, however the Mac Professional is unquestionably essentially the most attention-grabbing Mac within the Apple silicon transition. We might get a peek on the machine at WWDC with a launch doubtless in November or December.
M3–Late 2023/2024
Apple is already working the third-generation of its M-series processor, in response to The Info. It can doubtless be its first desktop processor to make use of a 3nm course of and provide a big velocity increase over the M1. It’s code identify is Ibiza
M3 Professional and M3 Mac—2024
We don’t know a lot in regards to the M3 Professional and M3 Max aside from their codenames are Lobos and Palma, and it’ll doubtless be 3nm.
Michael Simon has been overlaying Apple for the reason that iPod was the iWalk. His obsession with expertise goes again to his first PC—the IBM Thinkpad with the lift-up keyboard for swapping out the drive. He is nonetheless ready for that to come back again in type tbh.
