I’m interested in the pretty impressive performance delta – I wouldn’tve thought that Zen could outperform Broadwell quite so handily!
Me too! I’ll be completely honest: I have no idea what factors contributed here. Maybe things like no NUMA? a bit more cache? Something with Spectre / Meltdown? No idea – not my forte – but I am sure delighted by it.
EPYC is way more NUMA than Intel equivalents. EPYC has four dies on one package, and each die is a NUMA domain.
But Meltdown mitigations are indeed usually only turned on for Intel! :)
Disk possibly?
