AMD has yet to launch its AMD Zen 3 processors for servers, which are codenamed EPYC Milan, after the enormous success of these processors that have given AMD a presence in a market where a few years ago it was completely nil, now We are waiting for the AMD EPYC Milan of which we already know its performance thanks to Geekbench 4.
With Zen 3-based desktop CPUs on the market, and the impending introduction of notebook PCs, AMD still has two families of CPUs left to revamp the lineup: EPYC and Threadripper.
In servers his bet is the AMD EPYC, which are distinguished by having Italian cities as code names, if the EPYC Rome was based on Zen 2, EPYC Milan is based on Zen 3.
EPYC Milan performance on Geekbench 4
The CPU with which the performance tests have been carried out in Geekbench is the EPYC 7543 , which has a configuration of 32 cores and 64 threads , so we are talking about a configuration of 4 CCDs or Chiplets , and therefore we are not before the maximum configuration, since EPYC Milan like its predecessor EPYC Rome supports 8 CCDs or Chiplets and therefore up to 64 cores and 129 threads.
The EPYC 7543 is a processor with a base speed of 2.8 GHz and a boost frequency of 3.7 GHZ . Each Zen 3 core has 3 2 KB of L1 data cache and 32 KB of instructions and 512 KB of L2 cache . As for the L3 cache, it is 64 MB per chiplet or CCD , so we are talking about 256 MB for this level of cache in total for the 32-core configuration.
In Geekbench 4, in the single-core test the result obtained by the 32-core EPYC Milan was 6065 points , while in the multi-core performance test the result was 111379 points . This is more than enough for the EPYC Milan to far outperform not a single 28-core Xeon Platinum 8280 Cascade Lake, but two of them running at the same time and in parallel.
The evolution from EPYC Rome to EPYC Milan
As with the AMD Ryzen 5000 in various forms, the changes have occurred especially in the CPU cores, that is: in the CCDs.
Regarding the IOD that integrates the Northbridge, in charge of memory access and intercommunication of the different CCDs, and the Southbridge, there are hardly any major changes compared to Rome where the same configuration and the same type of IOD are maintained, so that Unless AMD has made any cosmetic changes to the processor organization, at first glance EPYC Milan should look the same as EPYC Rome.
AMD can add additional changes to the IOD of EPYC Milan, such as support for a greater number of AMD CDNA GPUs for data centers through a greater number of xGMI interfaces or support for DDR4 RAM with higher speed than those supported EPYC Rome
AMD will reign in servers for a few months
The next generation of Intel Xeon will appear when they launch those that are based on the Sapphire Rapids architecture, until that moment AMD will enjoy being at the peak of performance in terms of servers of all kinds.
These processors are not sold to the public directly but come from important contracts with several companies, for AMD to place its EPYC processors is a Trojan Horse so that AMD can offer its RDNA and / or CDNA GPUs and even the technology of the recently bought Xilinx from its customers.
Will Intel have time to respond or sooner than expected will we see a new generation of AMD EPYC based on the rumored Zen 3+? Who knows, at the moment we are looking forward to the presentation of the EPYC Milan that should not be too far behind in time.
