Intel Diamond Rapids "Xeon 7" CPUs Feature 256 P-Cores, The Same Number of Cores As Top EPYC Venice, Also Pack 1.28 GB of Cache And 12,800 MT/s Memory Support

Key Points:

• Intel's upcoming Diamond Rapids Xeon CPUs will feature up to 256 high-performance P-Cores based on the Panther Cove-X architecture, marking a 50% core count increase over its predecessor, Granite Rapids.
• These CPUs utilize Intel's 18A-P process technology and a new fan-out fabric architecture combining scalable compute building blocks, a unified memory fabric, and flexible I/O to optimize performance, efficiency, and scalability for enterprise-scale Agentic AI workloads.
• Diamond Rapids supports 16-channel DDR5 memory with speeds up to 12,800 MT/s and offers 128 PCIe Gen6 lanes along with CXL 3.0, enabling extreme bandwidth and IO scalability for next-generation AI and data center applications.
• The chip employs a disaggregated multi-tile design with four CPU chiplets and two large I/O dies, leveraging advanced packaging technologies like Foveros Direct 3D and UCIe-S interconnects to enhance integration and performance.
• Scheduled for release before 2028, Diamond Rapids will be succeeded by Coral Rapids, which will reintroduce simultaneous multithreading (SMT) and feature an 8-channel memory platform, aiming to meet rising CPU demand driven by AI workloads.
