AMD EPYC ‘Milan’ CPU Based On ZEN 3 Appears Online, Possibly With 32 Cores And Performance Rivaling Intel Xeon?

AMD recently launched the ZEN 3 based Ryzen 5000 Series CPUs. These desktop-grade processors are quite powerful, and it is only natural that AMD will also be developing CPUs for servers that are based on the ZEN 3 Core Architecture. It seems an early-stage Engineering Sample of the AMD EPYC server-grade CPU, codenamed ‘Milan’, may have leaked online.

Photos and information of AMD’s next-generation EPYC Milan CPUs have been published online. Although there’s no reliable way to ensure the authenticity of the information, it is quite possible that AMD has begun to test the new generation of EPYC server-grade CPUs that are based on the new ZEN 3 Core Architecture.

AMD ZEN 3 EPYC Milan CPU For Servers Being Tested:

AMD is expected to start offering the EPYC server-grade CPUs to companies and large tech firms early next year. Hence it is only logical that the company must have already developed prototypes of the new ZEN 3 based server CPUs, and started finetuning them. Now partial information about these CPUs has appeared online in the form of a single screenshot that appears to be of CPU-z software.

The CPU-z screenshot isn’t very detailed and only shows a partial section of the number of cores that seem to go up to 8. However, the scroll bar is obviously quite long, and estimating from the length, it is quite possible that the Engineering Sample of the AMD EPYC Milan CPU packs about 32 Cores.

Apart from the image, the leaker also claims the next-generation AMD EPYC Milan CPUs will feature single-core performance that will be on par with Intel’s top of the line Xeon CPUs. Although there’s no screenshot, the early benchmark of the alleged test was 500 points. It is quite likely that the leaker was referring to the CPU-z benchmark.

If the numbers are accurate, then the upcoming EPYC Milan CPUs with ZEN 3 Cores have a 23 percent jump in performance over the 2nd Generation EPYC 7742 CPU codenamed ‘Rome’. Correlating the numbers and estimation to Cinebench R20, these numbers would mean a performance jump of 25 to 30 percent in single-threaded workloads. Needless to add, this is quite expected from the earlier rumors which stated that EPYC Milan CPUs can feature around a 20 percent performance improvement over its predecessors.

Interestingly, the leaker added the testbench comprised of a dual-socket (2P) platform. Needless to add, such a platform is not meant for the consumer market and is reserved for top-tier EPYC chips. If the numbers and performance boost are accurate then Intel’s Xeon server-grade CPUs have a serious competitor in terms of performance and efficiency. The new AMD CPUs will compete with Intel’s Cooper Lake-SP 14nm and Ice Lake-SP 10nm CPUs which will be available this year.

Here’s a quick summary of the information about the ZEN 3-based AMD EPYC Milan server-grade CPUs:

  • Advanced 7nm Zen 3 cores (~64 core / 128 thread)
  • Pin Compatible With SP3 Socket
  • 120W-225W TDP SKUs
  • PCIe 4.0 Support
  • DDR4 Memory Support
  • Launch in 2020
