    Did you buy this system or is it on loan from Dell for review purposes? Configuring this server on Dell's online store gets it into the 5 figures very easily just from the CPU and memory options.

    what magic does stockfish and vgr do when 32->64 threads more than doubles performance?

    How much would cost a system like this?

    GraphicsMagick seems to scale with log(threads) instead of number of threads, until I miss something.

    Many results have a speedup of >> 2 when going from 32 to 64 threads, probably threads are not split evenly between packages.

    Phoronix: A Look At Linux Application Scaling Up To 128 Threads

    Arriving last week in our Linux benchmarking lab was a dual EPYC server -- this Dell PowerEdge R7425 is a beast of a system with two AMD EPYC 7601 processors yielding a combined 64 cores / 128 threads, 512GB of RAM (16 x 32GB DDR4), and 20 x 500GB Samsung 860 EVO SSDs. There will be many interesting benchmarks from this server in the days and weeks ahead. For some initial measurements during the first few days of stress testing this 2U rack server, here is a look at how well various benchmarks/applications are scaling from two to 128 threads.
