Isn’t there some promise that laser/light processing might become viable with nanolens technology? I think IBM has some interesting light processor prototypes.Lasers!
"nm" has became a moniker many years ago and does not reflect the actual size. They will simply go with a new naming scheme.Serious question. What happens when they get to 1nm? What’s the next step? .5, or some completely new technology all together?
Whatever Marketing Dept decides to call it. the "nm" term has had nothing to do with the size of circuitry, in many, many years. It is a marketing term.Serious question. What happens when they get to 1nm? What’s the next step? .5, or some completely new technology all together?
What a fantastic take. Completely agree!Apple learned a big lesson in releasing the M1 Macs back in Nov 2020. That is, you don't allow new generations of chip to come flying out of the blocks. They quickly learned that was a hard act to follow as the M2 chip was seen as nothing more than a speed bumped M1. For M3 Apple learned the lesson so that the new fab process will not allow all the dramatic gains to go out in the first iteration. M3 chips are neutered to only a 10% speed increase so that Apple can milk this in M4 and M5 generations. Then we get to this new fab process talked about here. It won't be generational but more neutering with a 10% spec increase to save the available additives for the following year's Macs.
All told, Apple Marketing is now following the Intel playbook to stretch technology gains over the lifetime of the fabrication tech. A truly garbage move by Apple.
nm is just a length like cm or km. In that specifically case not even the the physical dimension of the chips gates.Serious question. What happens when they get to 1nm? What’s the next step? .5, or some completely new technology all together?
lol well they showed off lunar lake today at their innovation event. And it was in a test laptop and it has already booted windows. It’s on 18A so it would appear that they’re on track.here, fixed it for you
IF
Isn't going from 5nm to 3nm a higher jump than going from 3nm to 2nm? The first is a full 40% size reduction, the second only a 33% one.Would be really cool that the first SoC built with the 2nm technology (and hopefully switching from FinFET to GAAFET), was the A20. “A20 Bionic, our fist 2nm chip.”
But I guess that depends more on TSMC and their roadmap. Let’s hope that the first 2nm chip will represent a much higher jump in performance/efficiency, not like the A17 Pro. Maybe the FinFET transistor technology is approaching its limits?
Thank you for taking that choice. You're one of those who's actions have a positive impact on this planet.This is why I prefer to replace my Macs, iPads & Watch 8-10 years later after their final Security Update.
I might do the same with the iPhone by 2027.
Raw performance, performance per watt and power consumption improvements would be the most pronounce by then.
At end of life hand it down or sell it to a collector.
Though note the marketing names don't represent the physical distances. The feature sizes for the current "3 nm" processes are quite a bit larger than 3 nm, and that will apply to "2 Å" as well. Thus you'd want to consider the quantum effects that correspond to the physical distances rather than the marketing names.0.2 nm, also known as 2 Å (for Ångström), is about as small as you can theoretically make anything with a semi-conductor material like silicon since that's the approximate distance between two atoms in the crystal. If we ever get anywhere near that with our current approach is debatable. Quantum effects become increasingly tricky to deal with as sizes shrink down to the level of atoms. More likely we'll have to hope for a major breakthrough somewhere else than shrinking transistors to keep advancing computing power at some point in the not too distant future.
In theory, yes. We’ll see how the N3E process go, the next mass produced node inside the 3nm family. However, the N3B node used on the A17 Pro is not delivering the performance or efficiency we were expecting from this jump, that’s why I said that.Isn't going from 5nm to 3nm a higher jump than going from 3nm to 2nm? The first is a full 40% size reduction, the second only a 33% one.
So, should we expect even less improvement in speed and/or battery life compared to what we just witnessed with the A17 chip?
its not proportional to physical size, its a marketing phrase.Isn't going from 5nm to 3nm a higher jump than going from 3nm to 2nm? The first is a full 40% size reduction, the second only a 33% one.

I do not do this for benevolence or virtue signaling.Thank you for taking that choice. You're one of those who's actions have a positive impact on this planet.
Hats off to you!
I miss the megahertz metric. It was a number that went up in the thousands then had that confusing stage when the numbers went down at least in 2 separate generations but the speed was faster anyways because of reasons. Having a metric that goes from 3 to 2 is not as exciting.
Not quite the full story.TSMC's 2nm GAA will focus on efficiency and low power performance which is ideal for Apple's designs. There will be less improvements in performance for the higher power designs that Nvidia focuses on.
Intel "Mass Production" is even more meaningless than TSMC mass production.If Intel executes on time, its 18A node will already have entered mass production. But that's a big IF.
Thank you for such a complete and detailed explanation of TSMC roadmap.Not quite the full story.
N2 brings two known separate, important improvements
- GAA. Better performing (faster switching, lower energy) transistors. Currently due late 2025 for TSMC
- BSPD. Move power lines to the back of the chip, reducing wiring congestion. Currently due 2026.
Note that neither of these exactly increases transistor density. Everyone will benefit from GAA in terms of higher GHz and lower W. Apple will benefit from BSPD since they are currently mostly limited by wiring density (hence the low density bump going to N3); nVidia will probably [I don't really know their design constraints] not benefit from the wiring density changes but both will benefit from the reduced power loss of BSPD (ie another small energy efficiency bump).
The most likely timing (but who can be sure) is an N2 with GAA then an N2+ with BSPD. But in principle the two could slide relative to each other, or even swap places. Of course Apple would like N2 ready for iPhones in 2025 but perhaps after the slippage on N3 (and forcing Apple to compromise on the A16) maybe neither want to take the risk? So maybe N2 iPhones in 2026, N2+ in 2027?
Of course there are other chips and other products! For example Apple might slip out some chip earlier on N2 for say Vision Pro...
At some point entering the mix is high-NA EUV. Right now no-one has given a timetable for that (except that the first machines should ship before the end of this year). Presumably, if there are no problems, this will be used for N2, giving higher density than otherwise expected; but high-NA EUV is not an essential part of N2 or N2+.
(Which means that numbers you see for N2 density relative to N3 are very tentative. Without high-NA EUV, N2 will be only 1.15x density of N3. Which is very much expected; the headliners for N2 are GAA and BSPD, not density.)
Intel showed off lunar lake today on Intel 18A. In a laptop running windows. It appears that Intel 18A is on track for 2025.Intel "Mass Production" is even more meaningless than TSMC mass production.
Intel will go through "mention", then "announce", then "manufacturing", then "releasing", then "shipping", and every one of these stages will be treated like the second coming. Meanwhile the gap between "mass production" and "can I buy it in Best Buy" will be a year or more.
Just don't be fooled. The same delay is kinda true on the Apple/TSMC side; the difference is that Apple doesn't trumpet it to the skies when in March they start manufacturing a chip you will only be able to buy in October.
Yeah - probably true in the time frame we’re talking about here, but Intel is investing a lot to pick up the ball they dropped (backed by Biden’s and the European Chips acts I suppose). At least I have more confidence in Intel delivering with Pat Gelsinger at the helm, but you do make some fair points…Not particularly creditable that they will get Intel 18 moving at the same time in any sort of respectable volume. Intel simply just doesn't have that many EUV fab machines . Indeed, from the same article quoting Gelsinger's comments.
True but the complaint factor will be 30% greater anyway.N3B vs N3E is an interesting comparison. N3E is actually slightly less dense, but expected to make a marginal gain in efficiency or performance.
