EPYC is decent, Xeon has a long way to go still. You mention actually measuring it, that's exactly what I've been doing in my top500 project: https://github.co

EPYC is decent, Xeon has a long way to go still. You mention actually measuring it, that's exactly what I've been doing in my top500 project: https://github.com/geerlingguy/top500-benchmark#results https://github.com/geerlingguy/top500-benchmark#results The RK3588 gets up to 4.64 Gflops/W, only beaten by a couple expensive Ampere Altra chips in my testing so far. A few of the newest EPYC chips touch that range, but none of the Xeons I've seen do (yet). I would like to test a few more but getting access to bare metal is tough, especially since I only need it for a day or two, but need to get it plugged into a consistent power monitoring device.
