Numerical Computing Performance of 3 Intel 8-core CPUs – i9 9900K vs i7 9800X vs Xeon 2145W

In this post I’ll take a brief look at the numerical computing performance of three very capable 8-core processors — i9 9900K, i9 9800X and Xeon 2145W All three are great CPU’s but there are some significant differences that can cause confusion. I’ll discuss these differences and see how the processors stack up when running Linpack and NAMD molecular dynamics simulations.

AMD Threadripper and (1-4) NVIDIA 2080Ti and 2070 for NAMD Molecular Dynamics

In my recent testing with the AMD Threadripper 2990WX is was impressed by the CPU based performance with the molecular dynamics program NAMD. NAMD makes a good benchmark for looking at CPU/GPU performance since it requires a balance and is usually limited by CPU. After some discussions I decided it would be good to look at multi-GPU performance with NAMD on Threadripper.

AMD Threadripper 2990WX 32-core vs Intel Xeon-W 2175 14-core – Linpack NAMD and Kernel Build Time

I recently wrote a post about building and running AMD Threadripper 2990WX with HPL Linpack – a “How-To”. Most of the time I had with the processor went into getting that to work. However, I did run a few other test jobs that I thought the 2990WX would do well with. I compared that against my personal workstation with a Xeon-W 2175. In this post I share those test runs with you. It’s not thorough testing by any means but it was interesting and I was surprised a couple of times with the results.
