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.
It’s easier said than done. A few key pieces took decades to figure out and even now many can only be produced by one or two companies, like ASML.
SMIC makes 5nm chips and is on the cusp of 3nm.
