Yesterday AMD held a special event in Rome, Italy, to talk about the momentum of its Epyc Rome processors, announce new partner platforms, performance milestones, and talk about new customers. HEXUS picked out the Dell EMC PowerEdge servers with 2nd Gen AMD Epyc processors announcement news to highlight on the news pages.

On the same day news of AMD's most powerful Epyc Rome processor yet came to light via AMD and French supercomputer partner Atos. The new AMD Epyc 7H12 processor is a variant of the 64C/128T Epyc 7742 server processor for liquid cooled systems.

In the official Atos press release you can see that the Atos BullSequana XH2000 supercomputer powered by an AMD Epyc 7H12 processor has set four new world-records in server performance. You will read that the system's enhanced DLC (Direct Liquid Cooling) was "essential in enabling the AMD's 280W Epyc 7H12 processor to reach its maximum level of performance," and achieve these records. For an example of its appeal, the AMD Epyc 7H12 in the BullSequana XH2000 achieved an 11 per cent increased HPL Linpack benchmark score compared to the Epyc 7742.

Getting to the nitty-gritty, the AMD Epyc 7H12 processor runs at a significantly faster base clock than the popular Epyc 7742 but has a slightly tuned down turbo clock and a hike in TDP. As you read in the Atos press release, you need an advanced liquid cooler to deal with its 280W.

With all the talk about TDP and liquid cooling above, one must remember that this processor is said to be very power efficient considering the record breaking performance results it can achieve. Atos says its BullSequana XH2000 supercomputer using the Epyc 7H12 will deliver "an optimal TCO (Total Cost of Ownership) enabling millions to be saved over the project lifespan".
