The Xeon Platinum 8180M is a beastly server chip. It has 28 physical cores and 56 threads to throw at workloads, and is clocked at 2.5GHz to 3.8GHz. The burly chip also boasts 38.5MB of L3 cache.
As for the Epyc processor, AMD did not share a whole lot of details, other to say it is a prototype 1P Rome platform. We do know it is a 64-core/128-thread processor, so even when combining the two top-shelf Xeon CPUs, the Rome CPU still flexes more cores and threads.
Obviously that presents an advantage, and we would expect the AMD chip to outperform the two Xeon processors, which it does. But what's impressive is that AMD crammed all of those cores and threads into a single socket while offering comparable performance per core. That is a big win in the server space, and it comes with certain advantages.
One of those advantages is highlighted in the video at around the 59-second mark when the group of AMD demonstrators comment on the noise output of the Intel system. "I hope the Intel box isn't getting too loud," Amit Mehra, principal member of technical staff at AMD, says to the group. Bob Hershberger, server system architect, then points out that the Intel system "is getting a little louder, which can be heard in the video.
