Epyc 7h12 is seen in geekbench with the super

A Geekbench 4 presentation today shows the power of two AMD EPYC Rome 7H12 64-core, 128-wire, server-grade processors on the Cray Shasta supercomputer. AMD added 7H12 to its second-generation EPYC line in September.

EPYC 7H12 is seen on Geekbench 4 again

AMD currently has three 64-core, 128-thread EPYC chips in its arsenal, though more may be on the way. With a 2.6 GHz base clock and a 3.3 GHz boost clock, the EPYC 7H12 is the fastest of the three existing models. The chip is rated at 280W, 55W more than the EPYC 7742, so the 7H12 should have a higher core clock.

The Shasta had two EPYC 7H12 processors, which means it had 128 cores and 256 threads at its disposal. The system achieved a single-core score of 4, 512 points and a multi-core score of 181, 580 points.

Surprisingly, Shasta's configuration was not enough to put the supercomputer at the top of the Geekbench 4 ranking. That accolade belongs to the Gigabyte R282-Z92 system, which carries a pair of EPYC 7742 chips. Shasta lags behind the R282-Z92 by approximately 3.4% and 7.6% in single- and multi-core scores, respectively.

On paper, the EPYC 7H12 should outperform the EPYC 7742. Due to the lack of detailed information, we can only assume that the discrepancy is attributed to the fact that both systems were running different memories, operating systems, and versions of the Geekbench 4 software.

EPYC Rome is based on Zen 2 architecture, the same as Ryzen 3000 and Threadripper 3000.
