Ryzen 3000 series performance

Skumball404 · 14 July 2019, 16:47

My current CPU is a 3770k and I'm looking to possibly upgrade this year to the new Ryzen 3000 series; either the 3900X or the upcoming 16 core version or even the upcoming Threadripper. However I've read concerning reports that going away from Intel for emulation in general is not the best move, however that could just be based on the older Ryzen lineup. Does anyone have experience with the newer AMD CPU's who can offer feedback on how they handle more complex emulators such as WinUAE, RPCS3 and the like?

Don't see why it wouldn't handle emulation, for your current CPU it's going to be a huge step up.

This is an interesting question

I soon must change my old notebook

Should i prefer a Intel CPU for WinUAE emulation ?

I am getting 3900X next week

Previous generation is slower in emulation that matching Intel, apparently Haswell and later versions have some optimizations that noticeably help code sequences that emulators regularly use.

EDIT: At least large L3 cache in 3000 series should help a lot.

I'd like to hear your feedback on the 3900X Toni!

Ryzen 3900X installed. 2*8G RAM 3600 (CAS latency 18) (Going to get 3733 2x16G sticks later with 17 latency). Asus ROG STRIX X470-F.

Not that useful WinUAE tests:

AIBB Sort: 80 -> 138, BeachBall 101 -> 150 (1886 -> 2357 JIT). Don't ask about SysInfo. It has too stupid code and so short code that emulation hot path probably fits almost completely in L1 cache.. I think my overclocked 6700k results were still slightly higher, at least in SysInfo..

AIBB probably also fits in L2 cache. Larger programs (or PPC emulation) probably are noticeably faster due to huge L3 cache.

WinUAE compilation is MUCH faster (at least over 2x faster)

EDIT: Above results are compared to Ryzen 2700X.

Excellent news, thanks for the report.
