AMD Ryzen 5000 series.

Post by gen_angry »

From what the presentation shows, they managed to hit an insane 630+ score on Cinebench single thread - which is incredible. Of course this is all carefully crafted PR puffery but it's pretty much the only bit we've got atm. If it's true, it'd be the first serious step above the Skylake-ish IPC 'stagnation' that we've had for the last 5 years where all the effort has gone into multi-core improvements and not so much single.

Do you think this massive bump in IPC/single threaded performance would translate to PCem performance? Especially since AMD is closing the gap pretty quickly on frequency alongside of being better IPC.

Maybe the 5000 series could reach the steep requirements for proper K6-II/Banshee emulation.

Not a clue. Let's wait until the chips are actually available before making conclusions about performance, okay?

On a Ryzen 5900x, I can get 100% with a K6-2 350Mhz + Voodoo 3 3000 at the Desktop and in some random 3D games. 85% with a K6-2 550MHz. (Of course, hard disk access causes stuttering because they are single-threaded AFAIK.)
Didn't test much else, I was just seeing what my new dev machine could do.

That's pretty awesome EluanCM. How does K6-2 performance compare with Pentium II for you? Is there a big drop in the highest attainable emulated clockspeed when you switch over to P-II?

Also, relevant to that "Skylake-era IPC stagnation" mentioned upthread: in a couple of months, Intel will FINALLY be debuting their first truly post-Skylake architecture (Cypress Cove) in the new Rocket Lake CPUs that will be coming out. They're promising a +10% IPC compared to their current-gen Comet Lake chips. Assuming that's accurate for the sake of argument, does anyone have any sense of where that would put Rocket Lake's single-thread performance relative to the latest Ryzens?

They're saying about equal, maybe margin of error off.

This competition stuff is nice :)

I don't have any P2 system set up, so can't measure right now. If I didn't miss anything from the commits leading to v17, the difference should be minimal. Found a few dynarec bottenecks with the K6-2 @ 350MHz:

Bottlenecks:
GTA2 stuck at 90-95%
F22 Lightning 2 stuck at 90-95%

Mixed:
Age of Empires 2 stuck at 70% in the menus but constant 100% ingame.

For completeness, these are always at 100%:
Forsaken, Outcast, Fallout 2, Quake, Quake 2, Age of Empire, among others.

Outcast is noteworthy as it is very CPU intensive - even though I didn't remember it being as clunky as it really is! :-(
I should do more tests in the future.

This is a completely factory default system, no headroom (PBO2, etc) was explored, it's air-cooled and it's summer where I live. Probably more performance can be extracted from this little beast.

What about Pentium II, Celeron?

I can run Intel Pentium II 450 MHz at 100% on my AMD Ryzen 5 5600X. Celeron 500 works around 80-90%.

Sure ? Did you overclock ?

No. Stock.

EDIT:

Midtown Madness 2 i can run at 100% on Pentium II 350 in Windows 95. Many other games works at 100% on Pentium 2 400 and 450.

May I ask if you could get games like Jedi Outcast or Jedi Academy to work well with your emulated P2 400 and 450? The Ryzen is a big improvement in CPU performance if it can run those 2 games through PCem at 100% on those 2 emulated CPUs.

Pentium II 450 runs at 100% on my 5900x but not all the time. At some points it can drop to 30%

I tried to run 3dmark 99 and the performance was terrible (this is when I reached 30%).
