wait isn't 7nm pretty good, the hacker news story about a new thing by intel used 7nm too https://news.ycombinator.com/item?id=37315802 probably you could do some stuff with enough 7nm chips
> a lot of tech breakthrus needed to overcome lack of access to EUVs, TSMC foundries & American RF supply chain
and not even use EUV at all? that is a pretty small number of nanometers
Keep in mind that Intel is years behind. TSMC N7 came out in 2018 so SMIC is ~5 years behind. Samsung 7LPP uses EUV but TSMC N7 and Intel 7 don't so it's not required. Without EUV, SMIC will probably be stuck at 7 nm for many years while other fabs reach 2 nm.
Mate60 has already been sold in China, but it is said that it is not sold to countries other than China. I wonder if there is any blogger who got this machine and filmed an explanatory video?
What does it actually mean when the 5G chip comes from a 7nm fab instead of a 5nm or 3nm? Does the battery have to weigh 1g more to supply the chip with the extra power and the phone have to be 1mm³ bigger to accommodate the bigger chip and battery, or will the numbers have be bigger?
I opened an old phone when I replaced it a few years ago, and described each part to my children. The chips didn't account for much of the volume.
I realise that a 3nm chip uses less power for the same processing than a 7nm chip does. Phones are mostly idle, though. Can receive/transmit 100Mbps or whatever, do receive/transmit very, very much less. I'd be thankful if someone who really knows about phone geometry/power could explain.

[ 4.3 ms ] story [ 39.8 ms ] threadWhich Chinese fab can make 7nm chips? I thought the best they have is 14nm.
Looks like the performance is similar to SD888 - which is not bad, but far behind the current SD8 gen 2.
