#72>1.6nm Gotta love how we now have fractions of a near meaningless metric.
Number represents transistor density. 2nm has ~twice the density of 4nm. If you ignore nm as unit of distance it makes sense.
This means that when different manufacturers use a different transistor design, their 'nm' process could be the same but their transistor density different.

You're the one calling it a feature size, not TSMC.
I’m sure you agree that the measurement given is a marketing term and is generally unhelpful beyond ‘it’s smaller than the current number’.
Just because you can't point to a specific feature and say that is 1.6nm, doesn't make the label meaningless as so many try to assert. It is a label that represents a process that results in a specific transistor density. What label would you prefer?

The link you give doesn't have any details of Intel's 18A process, including no indication of it innovating in any way, as opposed to TSMC with their "backside power delivery" which is going to be critical for power-hungry SOTA AI chips.

Intel has a 1.4nm process in the pipeline for ~2027. They just took delivery on their first high NA EUV machine in order to start working on it. Their gamble however is that they need to figure out DSA, a long storied technology that uses self-forming polymers to allow less light to sharply etch smaller features. If they figure out DSA, they will likely be ahead of TSMC. If not, it will just be more very expensive la…
Do you know the name of the company that produces the EUV machine? is it ASML? It is my understanding that only ASML had cracked the EUV litography, but if there's another company out there, that would be an interesting development to watch.

#78could someone ELi5 the backside power delivery please ?
ELI5: ICs are manufactured on silicon disks called wafers. Discs have two sides, and traditionally, everything was done on top. We can now do power on the bottom. This makes things go faster and use less power: * Power wires are big (and can be a bit crude). The bigger the better. Signal wires are small and precise. Smaller is generally better. * Big wires, if near signal wires, can interfere with them working optima…

Intel is the one trying to catch up to TSMC, not vice versa! The link you give doesn't have any details of Intel's 18A process, including no indication of it innovating in any way, as opposed to TSMC with their "backside power delivery" which is going to be critical for power-hungry SOTA AI chips.

thanks, I've fixed them btw, you appear to be shadow banned, probably on account of being downvoted for making short comments like "good" or "I don't get it" Short & simple responses may be adequate at times, but usually people will view it as not adding anything Perhaps reviewing guidelines https://news.ycombinator.com/newsguidelines.html will give an idea of the ideal being yearned for (granted, it's an ideal).

How can you tell someone is shadowbanned?
I vouched for barfard's comment in this thread
