Wonder what the price will be like on the 64-core high-frequency version... if it's comparable to existing Epyc pricing, this might be the obvious answer for a CFD rig in 2027. Finally something with memory bandwidth way greater than a Mac Studio…

If you're after high clocks I think threadripper has usually been the cheaper option than epyc

CFD performance is dominated by memory bandwidth, not clock speed.

dear lord that's a monster chip. 128 PCI-e v6 lanes. Looks like it's an TSMC N2 process and each CCD is 155mm2. That's a pretty large die, i wonder what kind of yields TSMC is getting on these.

Seems to be a multi die module.

Yeah, each die is 155 mm2 and the whole thing is around 2,000 mm2.
