Intel unveiled key package design and architecture details of its next-generation Xeon 7 Diamond Rapids processors, featuring a massive architecture overhaul with up to 16 CPU tiles and 1.28GB cache specifically to handle data-intensive agentic AI workflows.

Outlined at a Hot Chips 2026 presentation, the flagship Diamond Rapids CPU scales up to 256 performance cores (P-cores) paired with a massive 1.28GB pool of last-level cache. To achieve this density and performance (and to position the platform as a direct response to competing hyperscaler enterprise hardware), Intel went toward a highly disaggregated chiplet topology built entirely on its proprietary foundry nodes.

Diamond Rapids Details

The Diamond Rapids design is a multi-tile assembly comprising 22 distinct silicon components where the main package hosts 16 compute core chiplets fabricated on the Intel 18A-P process node, each housing 16 Panther Cove P-cores. These dies are vertically stacked using Foveros Direct 3D hybrid...
