CPU benchmarks

[gdkrmr]

I am looking for current server CPU benchmarks for HPC computing, any sources? This is not only for Julia but also library code (BLAS, FFT, etc.) and other programming languages (mostly interpreted ones, such as R and Python).

Especially interesting is the comparison between Intel and the new AMD processors, I heard that the AMD processors where (still are?) slower for HPC because of fewer floating point pipelines but caught up quite a bit with Zen 2 but Intel still has avx512 (which has its own set of problems). So the whole topic is currently quite complex and confusing and I don’t really have a good overview.

As I know - no Julia test yet …

  • Ryzen 3900X vs Threadripper 3970X / 3960X vs Intel Core i9 10980XE
  • MKL-DNN / DNNL ; Rust Prime benchmark ; PyBench ; R Benchmark ; … )

• phoronix: AMD EPYC 7642 Benchmarks: The Rome 48 Core CPU That Easily Takes On Intel’s Xeon Platinum 8280

• phoronix: 300+ Benchmarks With AMD Threadripper 3960X vs. Intel Core i9 10980XE

• servethehome: AMD EPYC 7302P Review A Category Killer

  • AMD: more cores, better I/O and PCIe Gen4 ( faster: NVMe SSD, GPU, Network )
  • Intel: AVX-512 ; VNNI (DL Boost.) ; Optane memory

bonus:

• Intel MKL faster with MKL_DEBUG_CPU_TYPE=5 on Ryzen CPU

Thanks, really interesting Seems like AMD currently is the better choice

AnandTech also does a ton of hardware benchmarking.
