During the European announcement for their 2nd Generation EPYC Rome processors, AMD unveiled their new and fastest EPYC chip, the EPYC 7H12. The processor is said to exceed the EPYC 7742 in terms of performance which was the initial flagship of the lineup but unlike the 7742, it’s specifically for liquid-cooled environments.

The AMD EPYC 7H12 is based on the same 7nm Zen 2 core architecture as the other EPYC ‘Rome’ chips around. The specifications include 64 cores and 128 threads which is the same as the other two 64 core variants in the lineup. Along with 256 MB of L3 cache and 128 PCIe Gen 4.0 lanes, the chip offers a top-of-the-line design. In terms of clock speeds, the chip is a completely different beast. The AMD EPYC 7H12 has a base clock of 2.60 GHz, the highest on any 64 core EPYC chip and a boost clock of 3.30 GHz which is just 100 MHz lower than the EPYC 7742.
