AMD Announces EPYC 7H12 Rome 7nm Zen 2 Liquid-Cooled Server CPU

AMD has lifted the lid on its latest server CPU, the EPYC 7H12. It stands as the most powerful EPYC line CPU the company has produced to date. It exceeds the capabilities of the already available EPYC 7742, thus taking the top spot as AMD’s flagship server-specific EPYC product.

AMD Rome Specs

As for specifications, the EPYC 7H12 uses 7nm Zen 2 architecture in line with other members of EPYC Rome platform and has 64 cores and 128 threads. It has 256 MB of L3 cache alongside 128 PCIe Gen 4.0 lanes. The base clock speed of the AMD EPYC 7H12 is 2.60 GHz, while the boost jumps to 3.30 GHz. The base speed makes it the fastest of the 7nm Rome 64 core CPUs by 350 MHz, the closest being the EPYC 7742’s 2.25 GHz.

The EPYC 7H12 is geared towards liquid-cooled server builds and with good reason. Liquid-cooling is a prerequisite to maintain the chip’s TDP rating of 280 W, a jump of 55 W from the existing EPYC 7742. It’s the highest TDP in the Rome 7nm Zen 2 lineup regardless of core count.

The boost clock speed is lower by a margin of 100 MHz, but the 280 W TDP rating means it can keep higher clock speeds across all cores for faster overall performance across the board. AMD reports that the 280 W TDP rating translates to an 11% boost in performance over the EPYC 7742, but we won’t be able to confirm this until the chip launches.

AMD says the EPYC 7H12 is designed to be compatible with the SP3 platform to ease the transition when switching over to the newer CPU.

AMD also revealed that the BULLSEQUANA XH2000 supercomputer would be powered by racks featuring eight of the EPYC 7H12. The high-efficiency hybrid machine is expected to be ready for action sometime next year.

AMD didn’t advertise a price, but given that the EPYC 7742 sells for just shy of $7,000, we can make an educated guess and expect the EPYC 7H12 to retail for close enough $10,000.

No release date was announced either, but we shouldn’t have too long to wait to find out when AMD hopes to launch the EPYC 7H12 in earnest.
