Russian PC makers cannot get Russian CPUs from TSMC, other foundries.
tl;dr: Intel and AMD are not selling their processors to Russia, and processors from Russian companies cannot be manufactured as Taiwan is banning TSMC from doing so, while Russia can only produce chips up to a 90 nm process.
China isn’t sanctioning Russia in any way; moreover, at the start of the war Chinese companies stepped in to alleviate some of the worst setbacks of Western sanctions. I think it’s fair to say that Russia would be in a far less favorable position without the support China has shown. I wouldn’t expect that situation to change any time soon. There’s always an innuendo of some brewing conflict between the two, but it’s just wishful thinking on the part of the authors.
