64-core AMD EPYC 7763 Milan server CPU makes cautious first appearance on Geekbench 5 in 128-core dual-processor configuration
The AMD EPYC 7763 processor is the top-end SKU in the upcoming Zen 3 Milan series of server chips. The 64-core, 128-thread part has a base clock of 2.45 GHz and a boost clock of 3.5 GHz with a 280 W TDP and 256 MB L3 cache. It’s a mighty chip that should light up synthetic benchmarks with its multi-core processing power. However, its first appearance on Geekbench 5 definitely appears to be a cautious approach to revelation rather than an example of shock and awe.
Where the 48-core EPYC 7643 amazed with a giant score of 33,348 points in the multi-core benchmark, this Gigabyte system that had two EPYC 7763 chips working in tandem for a total of 128 cores only managed to bring up 20,352 points. This muted result would leave the dual Zen 3 Milan processors behind in a comparison with the 28-core Intel Xeon W-3175X with its average score of 21,662 points.
There are many reasons why the 128-core, 256-thread dual-processor system didn’t impress by posting a score that soared over 50,000 points, which certainly seems possible when you look at what a 64-core Zen 2 Rome EPYC 7H12 managed in a similar dual-chip configuration (52,410 points). Software or driver issues, insufficient cooling or power delivery, background processes, benchmark misreading, early CPU sample, etc. – it seems more of a preparation run for the AMD EPYC 7763 before the real thing is fully unleashed.
