hmm.. interesting. Well I can't see shit. So I'll wait for the internet sleuths to put something together.When Zen 2 came out the 256FPU was very obvious and easy to see on the dieshots. It looked like the Zen 1 FPU was mirrored.
Found this Renoir dieshot with annotations. Fritz image is hard to see, but we can see enough to noticed that the FPU looks "thinner"?
edit: oh ^^ what a beast -- frankly scary amount of breakdown here from this. I feel like a child looking adult channels where the cable box is fuzzing me out.
