Intel SVP for architecture, graphics, and software, Raja Koduri, tweeted the first picture of the Xe HPC scalar compute processor multi-chip module, with its large IHS off. It reveals two large main logic dies built on the 7 nm silicon fabrication process from a third-party foundry. The Xe HPC processor will be targeted at supercomputing and AI-ML applications, so the main logic dies are expected to be large arrays of execution units, spread across what appear to be eight clusters, surrounded by ancillary components such as memory controllers and interconnect PHYs.

There appear to be two kinds of on-package memory on the Xe HPC. The first kind is HBM stacks (from either the HBM2E or HBM3 generation), serving as the main high-speed memory; while the other is a mystery for now. This could either be another class of DRAM, serving a serial processing component on the main logic die; or a non-volatile memory, such as 3D XPoint or NAND flash (likely the former), providing fast persistent storage close to the main logic dies. There appear to be four HBM-class stacks per logic die (so 4096-bit per die and 8192-bit per package), and one die of this secondary memory per logic die.
