Why would they go for more expensive dies when the performance improvement is minor?

or it could be AMD managed to widen the already massive efficiency gap against intel enough on the design end; they deem it not worth it to pay for an absolute bleeding edge node. That being said I could believe either way because they also have to worry about risc competitors too in enterprise.

So many variables so I will wait and see.

Wouldn't be surprised if these are just the IO dies while the rest is on TSMC's 3nm.

or things ya know, can change over the years; and Samsung finally is nearing node quality parity.
