AMD is showing pimping their Epyc 7H12, a variant of the 7742 server processor with 64 cores. The new SKU has a TDP of 280W instead of 225W. The base clock is 2.6 GHz instead of 2.25 GHz. The new CPU is the fourth Epyc server processor with 64 cores

The 64 core/128 thread, 2.6Ghz base frequency, 3.3Ghz max boost frequency, 280W TDP processor is specifically built for HPC customers and workloads, using liquid cooling to deliver supercomputing performance. The Turbo indeed runs 100 MHz slower, but considering the massive workloads, these servers benefit far more from a higher base frequency.

In an ATOS testing on their BullSequana XH2000, the new AMD EPYC 7H12 processor achieved a LINPACK score of ~ 4.2 TeraFLOPS, ~11% better than the AMD EPYC 7742 processor.
