Same. Did 12700KF to 14700K to pair with my 4090 on 1440p, so basically everything is CPU capped. It’s not drastic but it has certainly smoothed things out noticeably with a small bump in FPS. It’s likely the cheapest way (~$200 after selling 12th gen) to squeeze out a few frames without changing a bunch about your setup.

What makes you think they are stuck on 10 nm?
