If there’s something that gets everyone excited, it is more performance. On the Enterprise side, AMD has made big strides with its latest EPYC processor stack, featuring up to 64 cores per socket with 128 PCIe 4.0 lanes and 8-channel memory, featuring a very high performance per dollar in the marketplace. In order to coincide with the launch of the processor line-up in Europe today, AMD is unveiling a new chip to act as the new Halo product: the EPYC 7H12.

The new processor features a higher base frequency and a higher boost frequency that the previous top-of-the-line processor, the EPYC 7742. The new EPYC 7H12 has a rated TDP of 280W, and as a result the chip is being marketed for server environments that offer liquid cooled solutions only. AMD is very specific about this, especially in the market for which this CPU is aimed at. One of AMD’s main partners, Atos, is set to offer an 1U solution featuring eight of these CPUs, all liquid cooled.

For a base frequency, the EPYC 7H12 will be set at 2.6 GHz, and a turbo frequency of 3.3 GHz. Compared to the EPYC 7742, that’s +350 MHz on base and -100 MHz on turbo, for an increase in +55W TDP. The higher TDP means the 7H12 is expected to have an all-core turbo a lot higher than the 7742. The EPYC 7H12 is socket compatible with all other Rome processors.

With this new CPU, AMD is clearly going after the high-performance compute market. The chip still affords the same specifications as the rest of the stack, such as the PCIe lanes, the memory support, and security features, should any other market be interested, but AMD expects this CPU to be installed in large HPC datacenters. AMD published raw LINPACK metrics with a performance uplift of the 7H12 over the 7742 at around 11%.

We asked AMD if this is a chip designed for specific partners who can enable liquid cooling servers, or for any OEM that wants it. AMD responded stating the latter – this chip will have general availability, but given the target market, they are pushing it only for liquid cooled HPC systems. AMD states they have other processors better suited to certain other fields, such as finance.

We expect AMD’s OEM partners to be evaluating the 7H12 for their system offerings, with further announcements in due course.
