AMD has shown how an EPYC Rome overcomes a pair of 28-core Xeon Platinum



AMD has released a video on its official YouTube channel, which again shows the strengths of promising EPYC design processors in Rome. In the demonstration, the next generation EPYC-based single-processor system downloads a duet from the Xeon Platinum 8180M processors into the C-Ray test.

The Xeon Platinum 8180M is Intel's senior server processor for dual socket systems. It has 28 cores, supports Hyper-Threading technology, has a third-level cache of 38.5 MB and runs at frequencies of 2.5-3.8 GHz. In turn, specific details not yet published to EPYC with Rome's design remain unknown. The description of the AMD test system, however, refers to a single 64-core / 128-chip chip processor configuration. In other words, modular design of EPYC allows AMD to create one-core systems with a larger number of cores than Intel can offer in systems with two leading chip servers.

Obviously, the superiority in the number of cores gives AMD an advantage, demonstrating the results of the C-Ray benchmark. It should be clarified that the C-Ray benchmark evaluates the visualization rate using the beam tracking method and actively uses floating point calculations, the performance of which is significantly increased in Zen 2 microarchitecture. seconds while EPYC Rome managed to do the same work separately, 8% faster – in 28.1 seconds.

The presentation of EPYC Rome in the C-Ray test was officially revealed at the Next Horizon event in November last year and was no surprise. But now AMD has shown the live testing process and has also shared some details. So, AMD's decision actually won not just clean performance. It is obvious that future EPYCs are able to offer much higher socket performance than modern Xeon, which is an important factor for servers where this feature is important, such as a single-volume performance. In addition, in the demonstration, AMD officials point to another flaw in the competitive system: it works much more loudly.

AMD will continue to pursue aggressive policy in the server market segment. While the success of the company in this area is not very impressive. According to DRAMeXchange from the end of 2018, the company managed to win only 2% of the server market, but this result was achieved with the first generation of EPYC with a maximum number of cores of no more than 32. In 2019, AMD has set an ambitious plan to try to bite 5% share, and judging by the information that expires for the second generation of EPYC, it can actually become a reality.

At the moment, AMD does not reveal the detailed features of its second-generation EPYC processors. However, these 7-nm processors with Zen 2 microarchitecture can be expected to be able to replicate Intel server chips not only in terms of number of kernels and multi-threaded features but also in terms of price. The announcement of the promising EPYC design Rome is expected to be closer to the middle of the year.
