That is what I'm doing now, and your statements are correct. Using the Vega 11 only (not the CPU slot) gets me 16-17K PPD. Using the Vega 11 and CPU slot only bumps it up to about 20K PPD. Actually even with stock cooling the on board graphics don't generate much heat. I have my CPU fan profile set to ramp up quickly, but run quiet until 50C or so. With only the Vega 11 (I've been calling it the GPU slot though not a dedicated card) my temps stay in the 42-45C range. Adding any CPU cores naturally ramps up heat, fan speed, and power.muziqaz wrote:
If you have only fairly modern integrated GPU from AMD, it is always worth a try to set that going, providing you have good cooling. In most ases modern AMD integrated GPUs are theoretically a lot more powerful than CPUs next to them.
Interesting stuff, and now I see what you were doing regarding the cores/threads. In my case the CPU adds so little that I may as well quit folding with it. For the work it does the power and heat factor aren't worth it really. I could buy a really cheap dedicated GPU and accomplish more work for the power used.muziqaz wrote:

but
3900x@24threads produces 390k PPD
3900x@21Threads produces 300-350k PPD + 2thread slot of 16-17k + Radeon 7 with 1m-1.5m-2m PPD
When 21 Thread slot is running alongside 2 Thread one, boost is holding at 4075Mhz (which is probably upper limit for AVX256 workloads for the CPU), but AMD boost technology has been known to get the most out of CPUs, so if you pause 21 Thread slot and leave 2 Threads to run on itself, that 1c can boost to max ~4.4ghz.
The main 3000 series advantage over 2000 series Ryzens is full AVX256 support, instead of 2x128bit AVX on 2000 series. FAH still sees that as AVX256, but it kinda runs at half the speed of full AVX256.
So lets say my 3900x@21Threads is roughly twice as fast (in PPD produced) than my 2700x@15Threads which is pretty amazing.
With current influx of COVID projects which are quite small, my 3900x is not scaling to well, but still
Being I'm not a gamer and have minimal use for my computer these days, I just did the 2400G upgrade to keep life simple and cheap. But if I keep folding I might have to upgrade and buy a GPU so I don't feel like my system is in the stone age.
I'm glad to see that so many such as yourself are dedicating a lot of resources to FOH.
