GoKawiilIntel details Diamond Rapids Xeon 7 chips with 256 P-cores and 1.28GB cache
Intel unveiled architectural details of its next-generation Xeon 7 'Diamond Rapids' server processors at Hot Chips 2026, revealing a design with up to 256 P-cores and 1.28 GB of last-level cache, targeted for a 2027 data center launch. The chips use Intel's 18A-P process for core chiplets, add AVX 10.2 instructions, and switch from EMIB to UCIe-S packaging alongside Foveros Direct 3D bonding to link compute and fabric tiles.
GoKawiil's interpretation of the reporting above, not reported fact.
This reveals how Intel is restructuring its high-end server chip packaging strategy, moving away from its own EMIB technology toward the industry-standard UCIe interconnect, suggesting a push for broader compatibility and manufacturing flexibility. The massive core count and cache size also signal Intel's continued push to compete with AMD's EPYC lineup in demanding data center and AI workloads.
- Diamond Rapids Xeon 7 chips will offer up to 256 P-cores and 1.28GB of last-level cache
- Intel is adopting UCIe-S interconnects instead of its proprietary EMIB packaging for these chips
- The processors use the advanced 18A-P node and are expected to ship in 2027
