MAA Posted February 22 Share Posted February 22 Hello, 1) CPU Queen Why is the result of the newest Threadripper 7975WX worse than that 3970X (and even old 2990WX)? 2) FPU Mandel Why is the result of the newest Threadripper 7975WX worse than that 3970X? it should be twice as fast, as can be seen from the result in FP64 Raytrace.

It typically stops performing any better at around 30 cores. We're already working on a new Queen benchmark that would replace the current out-dated one in the next AIDA64 stable update. 2) Our suspicion is that there may be cooling issues about the 7975WX test system. We'll make sure to improve on that and re-measure the Mandel benchmark result. Quote Link to comment Share on other sites More sharing options...

It is scheduled for the next update. Quote Link to comment Share on other sites More sharing options...
MAA Posted July 25 Author Share Posted July 25 Why new 7.35.7000 CPU CheckMate benchmark do not have Threadripper 7975WX result? Quote Link to comment Share on other sites More sharing options...
MAA Posted August 11 Author Share Posted August 11 Why in ZLib the result of Threadripper 7975WX is almost the same as the old 3970X? Maybe need to use next gen Zlib? https://github.com/zlib-ng/zlib-ng Quote Link to comment Share on other sites More sharing options...

Other reason: the 7975WX system has SMT disabled, while the old 3970X has SMT enabled. Quote Link to comment Share on other sites More sharing options...

In certain heavy AVX-512 workloads with SMT enabled 7975WX performs worse than with SMT disabled. While in other workloads it's the other way round Quote Link to comment Share on other sites More sharing options...
