AMD EPYC 2 Rome v. Intel Xeon Scalable Cascade Lake-SP

AMD EPYC 2 Rome stacks up closer to a four socket Intel Xeon Scalable server. Even in many of those cases, AMD EPYC 2 Rome still has several points where it comes ahead. Intel will have Optane Persistent Memory and features like VNNI for inferencing. As we wrote in our Hot Chips 30 piece’s closing comments Intel needs more. These are technologies that are first generation parts that may become important in the future, but it will be some time before there is broad enough support to say that virtually every server will use both features every day.

Intel wanted to get ahead of the news and offer its own solution, the Intel Cascade Lake-AP. Intel has entered the multi-chip package arena with this announcement. First, Intel Cascade Lake-AP will almost certainly require a new socket. As it stands, Intel’s announcement of Cascade Lake-AP is a one-off product until Cooper/ Ice Lake arrive. In many ways, the Cascade Lake-AP dual socket architecture looks like a quad socket Intel Xeon Scalable system, just in two packages. As a result, the numbers should be close to the above 4P numbers, except with an asterisk that Intel may be able to get up to 256 PCIe lanes from their platform. That would give more lanes to Cascade Lake-AP and bring bandwidth parity with Rome.
