Threadripper 1950x low benchmark score

Hello everybody. I have setup a workstation based on a Taichi x399 and a TR 1950x and have been working on it without any obvious problems. Until I decided to benchmark the system that is. The score I get (on performance test 9.0) is 15742 which is too low in comparison to the average (about 21000). Any suggestions on what could be wrong? Thank you in advance.

I tested the CPU with Cinebench and the result seems to be normal in comparison (3019cb  @ 3.4) so I assume that it is an issue with PerformanceTest's optimization. (phew. I almost re-installed Windows).

If ANY test involves heavy CCX thread switching TR is dead in the water. CCX context switching is penalized heavily.

Then again, you never told us even what version of Windows you're using. Yes, we can see your screenshot and assume it's Win 10, however many folks claim TR needs 1703 and above for full potential to be utilized.

Worth checking if you have NUMA enabled or not, and flash the latest UEFI.

ventralstreams, that floating point result is really bad. Even my old Phenom II scored a lot better (7508 @ 3.7GHz, five run average), and so does my Ryzen 5 1500X (7992 @ 3.7GHz, five run average). In integer math you're doing less than 30% better than my Ryzen 5 1500X. Then again in SSE, encryption, sorting and compression your results are roughly 4 times better, which means these results have scaled with the amount of cores pretty well. Prime number and physics results are roughly twice what my 1500X achieves.

You can actually compare those sub results to other results with the same CPU directly from that screen by choosing the icon below the globe in the upper right hand corner, but I think it's pretty clear something's not right. Those CPU results should be pretty consistent between benchmark runs. Are you running the CPU in game mode or creator mode?

What about other benchmarks (in addition to Cinebench)? CPU-Z? Timespy and Firestrike CPU benchmarks? Geekbench 4.2?

That doesn't explain why OP's Threadripper seems to be performing a lot worse than other Threadrippes CPUs.
