The new chips, codenamed Milan-X, have the same capabilities as third-generation Epyc processors, but three times as much as the L3 cache. At the highest level, there is 768MB of L3 cache and up to 804MB of total cache per socket.
During the Milan-X architecture, AMD studied how technical computing applications work, and it turned out that a lot of cache was key to higher performance. This brings the data closer to the kernel, thus reducing the overall system response time. In addition, it supports Socket SP3, will be compatible with existing motherboards with a simple BIOS update, and use today's software without the need for modification. 2022. Cisco, Dell, Lenovo, HPE, and Supermicro have already partnered with AMD and will provide server solutions with these processors in due course. p>

If you can't wait that long, Microsoft Azure has a default HPC. The new chipset hardware is available today in private preview with a broader release in the coming weeks.
AMD offers 3rd generation Epyc Milan-X server processors with up to 768MB of L3 cache.
