Two additional benchmarks I like to see from Anandtech:
1) some VM base tests for these kind of CPU - 32, 64, 128 VM all running some kind of web/db/redis benchmarks inside.
2) Some compilation testing - time the clean build of AOSP, BSD, some very complex linux app - use max jobs setting for parallel compile and time how long it take to finish the jobs. ( measure the over CPU usages at the same time. )
- deng 8y agoThey do a compilation of Chrome in the "Office Tests" section. The 32Core takes about an hour per compile, but the 16Core is actually a bit faster (my guess would be that linking takes longer on the 32 core machine as it's very memory intensive).
- gsnedders 8y agoFWIW, I believe the version they use relies on a version of MSVC where the linker is predominently single-threaded, and linking the final binary ends up as a significant proportion of the time.
- twoodfin 8y agoDoes anyone do multithreaded LTO yet?
- glandium 8y agoGCC and clang do. As a matter of fact, MSVC does too, to some extent (CGTHREADS option, iirc).
- compilerdev 8y agoYes, the issue is the LTCG build, which by default uses 4 threads and with Chromium the compiler hits some pathological issues with such a huge program and it ends up using mostly 1 core and swapping lots of memory.
- MikusR 8y agoThere are Chromium compile tests. https://www.anandtech.com/show/13124/the-amd-threadripper-2990wx-and-2950x-review/9 https://www.anandtech.com/show/13124/the-amd-threadripper-29...
- CarVac 8y agoPhoronix had it compiling the Linux kernel in 32 seconds, compared to 37.5 for the 7980XE.
- xemdetia 8y agoEven more generally I would like to see some benchmarks being done of the VM extensions or other processor features. I don't know any benchmarks that helps you understand if the AES native instructions are any good or improved between models. There's a lot of chatter about the memory architecture but knowing that features like nested page table work well would be really useful for me personally.

- ksec 8y agoFor these kind of test I think Servethehome.com and https://www.phoronix.com https://www.phoronix.com does a better job.
