When the time comes I'll measure it just to make sure they don't lie.
1nm equals 10 Angstroms. A silicon atom is 1.92 Angstroms (0.192 nm) wide so process nodes cannot go smaller than that (and likely can't get close to that)So a techie question: 2025 is 2nm, then it will be 1nm. Where does it go to then?
The industry (TSMC, Intel, Samsung,...) counts in Angstroms (Ångström), 1nm = 10A. The 1.4 nm is labelled A14.So a techie question: 2025 is 2nm, then it will be 1nm. Where does it go to then?
Once Apple starts to take generative AI seriously, it will be.
Better performance per watt (efficiency?) and lesser consumption should lead to lesser heat with constant transistor density. However, the industry uses these advances to cram in more and more transistors, ensuring our hands never get cold in winter and our cats always find convenient sleeping places (aka cat-tops).You know what? We are still in need of even more efficient chips in the future. I though iPhones are now fast enough but Vision Pro? Rendering 3D environment in 23 megapixel in realtime and ends up with 2 hours of battery life is depressing.
I am not in the industry or even adjacent to it, but I love articles like that, and deep dives like Anandtech does. I watched this the other night and it blew my mind:The industry (TSMC, Intel, Samsung,...) counts in Angstroms (Ångström), 1nm = 10A. The 1.4 nm is labelled A14.

Lol, what? So I invented Coca-Cola, I guess. Just because they buy it doesn't mean they paid for its development. TSMC was gonna make a 3nm node with or without Apple, they have plenty buyers.It's chicken and egg with Apple's supply chain, behind every technology and R&D investment one should ask who's paying for it.
Good question! What will come after 1,4 nm?So a techie question: 2025 is 2nm, then it will be 1nm. Where does it go to then?

It is just a marketing label, it does not correspond to an actual physical measurement1nm equals 10 Angstroms. A silicon atom is 1.92 Angstroms (0.192 nm) wide so process nodes cannot go smaller than that (and likely can't get close to that)
Both Intel and TSMC are starting to switch to Angstroms for their process node descriptions - Intel's 20A and 18A are basically 2.0 and 1.8 nm equivalent process nodes, same with TSMC's forthcoming A14 process node (equivalent to 1.4 nm).
Once that limit is reached there are other ways to keep driving performance forward, such as 3D lithography, looking to new materials, or continual improvements to existing process nodes.
What is important is that there is a performance per watt improvement.It is just a marketing label, it does not correspond to an actual physical measurement
I just don't agree with the few articles that have mentioned about possibly having the M4 come out on the 2nm node in 2025. It makes way more sense for the 2nm to be on M5 at the least as Apple just began the 3nm with M3.
It makes more logical sense for Apple to have the M4 on N3P or N3E near the end of this year before moving to 2nm.
I think I will wait for M10 on -5.0nm tech.So -
M4 Q4 this year - enhanced 3nm. (Sort of M3S, like the M2 was?)
M5 Q4 2025 with 2nm.
M6 2026 with enhanced 2nm?
M7 2027 with 1.4nm.
Is that about it?
Lots of presumptions in that about peoples work flows.Once Apple starts to take generative AI seriously, it will be.

How M1 Macs may lag behind
M1 CPUs support ARMv8.5A, which doesn’t support the new bfloat16 floating-point format now widely used in AI. That’s likely to put them at a disadvantage.eclecticlight.co
M4 will likely land around February 2025.So -
M4 Q4 this year - enhanced 3nm. (Sort of M3S, like the M2 was?)
M5 Q4 2025 with 2nm.
M6 2026 with enhanced 2nm?
M7 2027 with 1.4nm.
