Was 7nm a requirement? I didn’t gather that from the thread.

Small run 22nm is certainly available. These are fabricated in the US, albeit at an Intel site. https://www.mosis.com/pages/intel_sponsored_fab

I mean the article is about them building a 5nm fab in Arizona, so i assume they do need it if they want to build fast AI chips that compete with China should it invade Taiwan.

What’s a fast AI chip? :)

What process node Google uses for TPU, one possibility for an AI chip, is not in the public domain since v1 but it’s very unlikely this chip is on the bleeding edge. Cost/benefit is likely not there for this use case. But only Google knows for sure since they run the cloud and get to define “benefit”.
