The Cinebench R23 score of the AMD Epyc Milan flagship CPU has been shared by “ExecutableFix” on Twitter. The sample tested was running at a boost clock of 3.7GHz in a 2S socket configuration.
In the single-core test, the Zen 3 powered server processor scored an impressive 1,215 points. That’s nearly 25% faster than its predecessor, the AMD Epyc 7702P which nets 990-1,000 points in the same test. While 10-15% of the total gain comes from the IPC increase, the rest comes from a considerable increase in the boost frequency: 3.7GHz vs 3.35GHz.
With Milan, AMD is focusing on the single-threaded performance similar to the Ryzen 5000 lineup. On the multi-threaded front, the Rome CPUs already have a massive lead over their Intel rivals. This increase in ST performance pretty much leaves you with no reason to opt for a Xeon chip.
Intel plans to launch its Ice Lake-SP (up to 32 cores?) in Q1 2021, right around the time the Milan parts will be officially announced. However, we don’t expect Ice Lake to be much faster than Milan in terms of single-threaded performance. The difference should in the lower single digits which is more or less irrelevant as server workloads are multi-threaded and mostly deal with large amounts of data.
