SMIC makes 5nm chips and is on the cusp of 3nm.

[โ€“] TheGrandNagus@lemmy.world 1 points 2 years ago

Marketing terms mean nothing. SMIC's nodes are nowhere near the real transistor density of TSMC's or even Intel's.

But what's worse than that are the yields. I don't believe we have public numbers on their newest node yet, but their self-reported yields on their "7nm" process as of late 2022 was a pathetic 10-15%. TSMC's 7nm yield (and you should remember that TSMC's 7nm is vastly superior to SMIC's) was getting over 70% yield when it was in pre-production trialing.
