If you examine the CPU industry and ask where the big money is, you have to look at the server and datacenter market. Ever since the Opteron days, AMD's market share has been rounded to zero percent, and with its first generation of EPYC processors using its new Zen microarchitecture, that number skipped up a small handful of points, but everyone has been waiting with bated breath for the second swing at the ball. AMD's Rome platform solves the concerns that first gen Naples had, plus this CPU family is designed to do many things: a new CPU microarchitecture on 7nm, offer up to 64 cores, offer 128 lanes of PCIe 4.0, offer 8 memory channels, and offer a unified memory architecture based on chiplets. Today marks the launch of Rome, and we have some of our own data to share on its performance.

First Boot
Sixty-four cores. Each core with an improved Zen 2 core, offering ~15% better IPC performance than Naples (as tested in our consumer CPU review), and doubled AVX2/FP performance. The chip has a total of 256 MB of L3 cache, and 128 PCIe 4.0 lanes. AMD's second generation EPYC, in this case the EPYC 7742, is a behemoth.[/URL]
