SF nnue off: 1399478 nps
SF nnue on: 1830004 nps (!!!)
= using nnue is 131% speed compared to nnue off
That looks too good to be true.
This is what I get on my Ryzen 9 3900. Fresh booted system, offline.
The nnue off numbers look low to me. My mobile chip gets 1673 knps while your desktop Ryzen-9 gets only 1399 knps. Something is wrong.
The Ryzen is build in a notebook. So, I set the CPU speed to 95%, to prevent it from overheating, which means constantly 2.9 GHz (switches off the TurboBoost), nonetheless 1 Thread or 24 Threads are used.
Speed measuring of singlethread engines lead to wrong resuls, if the CPU is running at 100%. Because of the TurboBoost.
So, perhaps your results are wrong
I kept an eye on the clocks. In both runs it was boosting in the same 4.8-4.9 range, so there was no significant difference and it is not a factor in the comparison.

Amazing results.
Could somebody do the same test with the Ryzen 7 3700x?
3700x, manual overclock @4300 MHz
sf 13 avx2
1 thread, go depth 28
nnue off: 1,980,523 nps
nnue on: 1,826,595 nps (92%)
16 threads, go depth 28
nnue off: 21,893,048 nps
nnue on: 19,614,930 nps (90%)
Nice result. I am thinking about getting a 3700x, but I don't want to OC it. How would it do it without OC?
At that frequency, do you need a special cooling system for the CPU?

Seriously?
You're the only one here with a ratio far above 100% amongs a few users with an AMD processor. MikeB got 92%. I get 91%, Elpapa 90%, Modern Times 94%. You get 131% and you think that perhaps other's results are wrong?
When I run my machine in base clock I get a ratio of 91.9% = 1212842/1319436:

It's not really an overclock as I see it, more like a constant frequency which I prefer. The CPU is stable at 1.225V so it doesn't need any special cooling, but the stock cooler made some noise under heavy load. I bought an Arctic Freezer eSports Duo and changed the fan curves and now I can't hear the fans at all.
I can run the same sf benches later with stock settings if you want, but I think it's about 10% faster with current settings, including memory OC.
