  • Michael Larabel - MichaelLarabel.com
  • Phoronix
  • Started in 2004 - first test suite published in 2007.
  • Other business models like specCPU
  • Phoronix lastest ARM server results
  • Still getting Linux kernel regressions but more rare.
  • Asrock motherboard is very reliable/afordable. Supermicro, Asus, Gigabyte also good to look at.
  • Measuring memory copy time to GPU - making sure it isn't confused with GPU processing times.
  • What makes a good benchmark? Core count scaling is more important than it was. More than 64 core scaling is still challenging.
  • Top compiler/kernel improvements in the past 20 years - propper PCIe power configuration (20 watt improvement) - better optimization configurations for gcc/llvm defaults - Intel's P state driver.
  • AMD/Intel now very competitive - larger cache sizes.
  • CUDA is still dominating the GPU market. OneAPI and SYCL are promising.
