Intel Xeon MAX 9480 deep dive: 64GB HBM2e on board

Today we have something that has taken months to write, and we feel that the best we have done is to give a sense of what Intel’s coolest CPU is capable of. The Intel Xeon MAX 9480 combines 56 cores with memory on the package. The memory is not standard DDR5. Instead, it is 64GB of HBM2e, the same kind of memory found on many GPUs and AI accelerators today. What seemed like a straightforward review at the outset became absolutely fascinating, especially when we pulled all of the DDR5 memory from a system and watched it boot. Let us get to it.

Few of us will ever get to use one of these – especially since they’re specifically designed for a supercomputer – but maybe we’ll get lucky and they end up on eBay or AliExpress ten years from now.
