Zen 3 has been showing off its performance chops once again, this time in the form of an upcoming server processor from the Milan series. Tum Apisak noticed a record for the AMD EPYC 7543 as part of a Wiwynn server on Geekbench that revealed the Milan chip had 32 cores and 64 threads, registered a base clock of 2.80 GHz, and it could utilize a massive 256 MB L3 cache, just like the current 32-core Rome processor EPYC 7532. While the single-core score was expectedly unspectacular at 1,343 points, the multi-core score was remarkable at 25,909 points.
As always with these kinds of reports, the results should be treated as a theoretical maximum until more tests are made. However, it’s still interesting to compare the AMD EPYC 7543 with the current Geekbench benchmark multi-core chart leaders: the 64-core AMD Ryzen Threadripper 3990X and the 28-core Intel Xeon W-3175X. The Milan part’s score held up extremely well against these two powerful rivals, with the multi-core score being +3.53% more than the 3990X’s average result (25,025 points) and a noteworthy +15.01% up on the Intel Xeon W-3175X (22,527 points).
Of course, the EPYC 7543 has a 4-core advantage over the Intel part and it has Zen 3 microarchitecture to fall back on. The Milan part’s performance in comparison to the 64-core Ryzen Threadripper 3990X is impressive though. AMD CEO Lisa Su gave a recent taster of how powerful 3rd Gen EPYC processors are by showing two Milan 32-core chips completing a weather forecast 68% faster than two Intel Xeon Gold 6258R processors.
