Supermicro Sets World Record Performance with AMD EPYC Processors
There are the new cpus Epyc 7fx2

These cpus on Rosetta (maybe with SSEx/Avx instrunctions!!) will be great. :-P

*drool*

I wish I could afford even one of those. Even a Ryzen 9 is a bit too rich for my finances, though.

Yeah. I used a web site to set up a new system (just in case i won the lotto) based on a Ryzen 9 3900X.
$3,000 and a bit (and that's without a video card, i'd use one from an existing system).

The AMD EPYC 7Fx2 series is intended for applications that benefit more from frequency and cache, over raw thread count. However, Rosetta@home is perfectly able to use as many threads as a system has available (provided that the machine has sufficient RAM).

While these frequency-optimized SKUs are impressive for their intended workload, they wouldn't be optimal for Rosetta compared to the existing 2nd generation Epyc lineup.

Isn't Rosetta L3-Cache hungry?

Is it correct that as time goes on, L3 cache will eventually turn into "RAM"? I remember having a computer with 64MB of RAM... and now we have a CPU with 256MB of L3 CACHE.

Any large application, or application that uses large data structures will be "cache hungry", and will perform better with a larger cache available.
