Now that we have the M3 series out I think we can probably begin to predict when Apple will release its next chips.
The M1(5nm)series will probably become the longest generation overall without an update, and that would probably be due mostly to chip shortages at the time, but all in all that generation went about 20 months before an update, and the updates began to roll out with the M2 around WWDC 2022.
The M2 Series (5nm, improved fabrication technique),building on top of the architecture of the M1, went on for about 17 months until the M3 was introduced. A rumored “extreme“ variant was rumored but never materialized for whatever reason, if it was in fact even real.
The M3(3nm) series is unique in that pretty much all of the chip family other than the Ultra and a possible “extreme“ version was introduced. Apple also apparently has a deal with TSMC so to make sure they had all of the 3nm production and a jump start on 3nm tech, I would guess this is why they released all these machines when they did, and all next year we will see iPad and lower end Mac refreshes throughout the year using the M3. Because of the Apple Vision Pro, I can’t see Apple releasing any of these new computers until WWDC, with the last of them coming around Oct of 2024. If an ”extreme” were to be released, I wouldn’t expect it until late 2024, early 2025. All in all, I would guess this processor family goes for 16-18 months before M4 is released in 2025.
The M4 (3nm improved manufacturing process) if the M2 is like a “M1S” then the M4 would definitely be the “M2S” I think a lot of this really depends on if they have any new products that could take advantage of the 3nm chip such as an updated Vision Pro, but judging by how the M2 generation was released, we will get these chips around WWDC 2025, with the last of them probably released around October/November of 2025. I would guess this generation last even shorter Than the M2 generation did, at around a year tops as Apple likely is expecting demand to soften with these chips as well.
The M5 (“2nm” my understanding its not really 2NM just a far more dense 3NM) would at the earliest come in late 2025, but for Apple’s computers I think it is far more likely they release the computers that use these chips in 2026. My reasoning behind that is that as far as I know, first run of these chips won’t even begin until first half of 2025, and full run won’t begin until the second half, which if Apple plans to use these for iPhones and such, I wouldn’t even be surprised if there was a delay in iPhone‘s launch at the end of the year to October/November.
So what do you guys think? Does this all sound reasonable/ realistic for Apple to follow A timeline like this? Also for reference, there is a graph from Wikipedia below to show when each of the current chips were released.
