EPYC Rome CPU Product Stack
It all starts with the EPYC 7252 at the bottom of the stack, as an 8C/16T chip, 120W TDP, CPU clocks of 3.1/3.2GHz for base and boost, respectively. It has just 64MB of L3 cache compared to the 128-256MB on the other CPUs in the EPYC Rome stack of chips.
But at the top we have that glorious EPYC 7742 with its beasty 64C/128T of brute CPU performance, with a 225W TDP, 256MB of L3 cache (!!!) and 2.25/3.4GHz base and boost CPU clocks, respectively.
All of the new second-gen EPYC processors have 8-channel DDR4 support at up to 3200MHz, and an insane (and game-changing) 128 PCIe 4.0 lanes.
The 1P list of CPUs is shorter, but there's options for everything here from 8C/16T right through to the 64C/128T in the EPYC 7702P.
