Michael Larabel of Phoronix has conducted a test of Linux application scaling on up to 128 threads. He chose a Dell PowerEdge R7425 server featuring two AMD EPYC 7601 processors for a total of 64 cores and 128 threads, 512GB of RAM (16 x 32GB DDR4), and 20 x 500GB Samsung 860 EVO SSDs. He ran the server through a battery of testing to see how Linux applications and benchmarks scaled from 2 threads to 128 threads. He has even more results here. If you are curious about how much AMD EPYC processors cost in relation to Intel Xeon processors, the AMD EPYC Processor Selector Tool is found here.
