Intel Expands Israel's Role in 256-Core Diamond Rapids Server Design

Summary
Diamond Rapids will underpin Intel’s next Xeon server chips with up to 256 cores, and the company said its Israeli R&D center led development of the architecture’s core computing unit.
Four modular CBB units—each with up to 64 cores—are designed to operate as one cluster with consistent memory access, giving Intel a flexible server architecture for different data-center configurations.
The broader mandate marks a step up from Israel’s earlier Xeon work on performance cores alone, after the team’s Lunar Lake laptop work on performance and power efficiency was extended into server design.
Intel is pitching the architecture into rising AI data-center demand, arguing CPUs still matter for model execution and other workloads even as GPUs dominate training and newer autonomous AI agents lift compute needs.
Israeli engineers also added security features to keep data isolated and encrypted across expanded memory and to verify a server’s protected state before sensitive information is sent.
