Compared to your results for the WX9100 BIOS, I seem to get uniformly higher performance with the 220W MI25 BIOS. The difference is roughly comparable to the difference in power limit (but not exact).
| BIOS | power | pp512 | pp2048 | pp4096 | tg128 |
|---|---|---|---|---|---|
| WX9100 | 170W | 301 | 369 | 363 | 36 |
| MI25 | 220W | 436 | 430 | 421 | 39 |
| ratio | 1.29 | 1.45 | 1.17 | 1.14 | 1.08 |
This is of course a not a properly controlled experiment, as our systems are likely different. I am running the latest llama.cpp (tag: b10069 from July 19) .
I am picking up some performance improvement … somehow.
