I'm confident Samsung did some of the 21264s which would be 250 nm as well.

https://www.samsung.com/us/news/newsPreviewRead.do?news_seq=173

I think there was a 180 nm version of the 21264 they did too and released in either 2000 or 2001 that scaled the design to 1 Ghz. Not much emphasis was put on it as the 21364 was coming.

Agreed but more of a historical note that they have had experience with high clock (for the time) and large dies.
