It's my own results for Intel processors:
Xeon E5-2650 - 700-800 H/s (8 cores 16 threads)
i5-6700 - 600-650 H/s (4 cores 4 threads)
Pentium G4400 - 300-330 H/s (2 cores 2 threads)
processors at stock clocks.

Maybe should be checked 2011 socket server processors for best profit per $

This is not about withdrawal, but aboout that almost all of us lost aout coins at pool  because of switch to a new server and there are some problems, but there is work underway to fix that all.

used servers are cheap on ebay.

under 500  but free power  is why he makes money.
