AMD Releases Higher Clocked Epyc Server Processor with 64 Cores

AMD comes with the Epyc 7H12, a variant of the 7742 server processor with 64 cores. The new variant has a TDP of 280W instead of 225W. The base clock is therefore 2.6GHz instead of 2.25GHz. Atos will use the chip in supercomputers.

The new CPU is the fourth Epyc server processor with 64 cores. AMD announced three of them more than a month ago. The new model has a higher TDP and therefore a higher baseclock, but the maximum turbo frequency at 3.3GHz is slightly lower than the maximum speed of the Epyc 7742, which goes up to 3.4GHz. AMD does not provide an explanation for that difference in the announcement. Presumably the all core turbo of the 7H12 is higher than that of the 7742, but AMD does not specify that speed.

According to measurements taken by Atos, the Epyc 7H12 outperforms the Epyc 7742 by 11 percent in the Linpack benchmark. Atos will use the 7H12 in its BullSequana XH2000 platform for supercomputers. Water cooling is required to get the maximum performance out of the chip, AMD says. The manufacturer does not disclose a price for the Epyc 7H12 variant. The previously released Epyc 7742 has a suggested retail price of $6950.
