The US Sanctions weren't meant to stop sub-14nm processes despite what Redditors said. The main point was to keep a 3-5 year lead on Process R&D.<p>That said, I've found the policymaking around the whole Semicondutor space very infuriating. There's a lot of blowhard bullshit going on, and in an actual shooting war we'd be seeing larger sized chipsets used (eg. 14nm, 28nm, etc).<p>You don't need computational performance for a precision missle - it's anyhow going to crash itself.<p>And any attempts as slowing Chinese simulation/Exascale compute would have anyhow failed as<p>1. The sanctions only target military, not educational and private sector players despite China's robust MIC<p>2. Parallelism can make up for any raw compute losses.<p>I have some additional thoughts about this having worked with some of the people writing these policies but ehn
