The Incredible Performance & Power Efficiency Of AMD Zen 1 vs. Zen 4C

The Incredible Performance & Power Efficiency Of AMD Zen 1 vs. Zen 4C: While we are beginning to see AMD Zen 4C cores in client systems, these smaller cores have already proven themselves very interesting and capable with the AMD EPYC Bergamo high core count server processors and the extremely power efficient EPYC 8004 "Siena" processors. For showing how far Zen has come in power efficiency, I thought it would be fun to show how the original flagship EPYC 7601 "Zen 1" processor with 32-cores / 64-threads compared to Zen 4C with the EPYC 8324P(N) 32-core processors. But as that isn't even the top-end Siena part, I also tossed in the 64-core EPYC 8534PN too for a top of stack look for the current EPYC 8004 line-up.
