Worth noting that 3nm FINFLEX doesn't seem scale that well for higher-end performance chips (the 3-2 fin configuration):
Even if GPU makers use the 2-2 configuration and the node is no more expensive than that price estimate, both big ifs, that's only a 10% increase in transistor density per $, which is really bad.
That means we'll likely enter a lull on performance improvements for quite a while since even the nodes coming beyond 2024-2026 (3nm single-fin and 2nm nanosheet) aren't much better than what you see above.
