AMD EPYC 7643 Milan server chip uses its 48 cores to generate an amazing Geekbench 5 multi-core result that easily keeps pace with the 64-core Ryzen Threadripper 3990X

The 48-core AMD EPYC 7643 Zen 3 server processor has made another appearance on Geekbench, turning up on version 5 of the synthetic benchmark. The Milan chip pulled out a gigantic multi-core score of 33,348 points that puts it +33% ahead of the average result managed by the 64-core AMD Ryzen Threadripper 3990X.

The EPYC 7643 server chip has been spotted on Geekbench 5 by Leakbench producing a mighty multi-core result. Not that long ago, the same SKU appeared on Geekbench 4 and pulled off a similar magnificent multi-core performance that left just about every other processor in its wake. The 48-core, 96-thread part managed 1,256 points in the single-core test and 33,348 points in the multi-core run. Operating inside a Wiwynn server, the EPYC 7643 was recorded at a base frequency of 2.30 GHz and reached clocks of just over 3.4 GHz.

The Milan Zen 3 processor, which was at a stepping level 1, would be far and away the leader of Geekbench’s charts for the multi-core run. However, even though it was mentioned above that the EPYC 7643’s result of 33,348 points is +33.14% more than the current leader’s 25,047 points (Ryzen Threadripper 3990X), this is a theoretical maximum against an average. But, looking through the scores recorded for the 64-core HEDT Ryzen part show that the higher scores are at a similar level in general to what the EPYC 7643 managed, even with the former’s 16-core advantage and higher boost clock (4.3 GHz).

The 3rd Gen EPYC Milan Zen 3 server CPUs are expected to be released at some point in March. A recent server chip comparison list shared by the data-miner momomo_us showed that the EPYC 7643 isn’t even the most powerful member of the Milan family, with a 56-core EPYC 7663 and three 64-core parts yet to rear their heads on Geekbench. It will be interesting to see what kind of multi-core score the 64-core, 280 W EPYC 7763 will produce when it finally gets publicly tested.
