They aren’t talking about yields, so I assume they can make fast chips but suffer on yields. The same is true with jet turbines and why they are still using Russian ones in the military and western ones for their civilian planes. They can make high performance, but the fly time between overhaul is too low to be economical.
But China can afford to subsidize $1000 chips, especially if that means not having any chips at all.
- alephnerd 3y ago^^^ why is this downvoted?!?! Nothing is wrong in this statement.
- seanmcdirmid 3y agoThat is just about mianzi, no worries. Anyways, after reading the articles, it sounds like they are using older ASML lithography equipment, rather than homemade equipment from SMEE. Which is strange, because they announced they can do 3nm, but they are only putting 28nm into production this year. https://abachy.com/news/chinas-28nm-lithography-machine-expected-2024 https://abachy.com/news/chinas-28nm-lithography-machine-expe...
- alephnerd 3y agoI mean it makes sense. Most vendors can do 3nm, but probably not at production scale other than ASML. 28nm is very worrying from a NatSec standpoint though - way more than leading edge nodes - as that enough to produce a Sandy Bridge or Maxwell type architecture, which meets the needs for most American defense applications (eg. drones, precision missiles, C-RAM, etc) Russia manufactures their Elbrus-8s architecture using 28nm lithography as well, and that's the backbone for most of their newer precision, electronics, and avionics weapons systems.
