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

Intel has detailed its next-generation server architecture, known as Diamond Rapids or "Xeon 7," during the Hot Chips 2026 event. According to reporting from Wccftech, these CPUs feature 256 P-cores, a core count that matches the top EPYC Venice offerings. The technical specifications revealed for the Xeon 7 include 1.28 GB of cache and support for memory speeds reaching 12,800 MT/s. These hardware advancements are positioned as part of Intel's broader strategy to outline architectures specifically designed for agentic AI, as noted by the Intel Newsroom. Coverage from multiple outlets, including TechPowerUp and Wccftech, emphasizes the package design of the Diamond Rapids processors.

TechPowerUp specifically highlights the details shared at Hot Chips regarding the physical and architectural layout of the Xeon 7. Furthermore, the Intel Newsroom reports that these developments are tied to a larger push for agentic AI capabilities across their product stack. The technical scale of the 256 P-core configuration is presented as a direct competitive response to the core counts found in the EPYC Venice lineup. Context for these announcements includes a significant expansion of Intel's research and development efforts in Israel. According to calcalistech.com, Intel is expanding the role of its Israeli R&D center in conjunction with the unveiling of this next-generation server architecture.

This structural shift coincides with the introduction of the Crescent Island GPUs, which Wccftech reports pack up to 32 Xe3P cores. These GPUs are optimized for agentic AI and utilize low-cost LPDDR5X memory that can reach capacities of up to 480 GB, providing a complementary hardware ecosystem to the Xeon 7 CPUs. Future developments to monitor involve the integration of these Diamond Rapids CPUs and Crescent Island GPUs within data center environments. The industry will be looking for the implementation of the 12,800 MT/s memory support and the 480 GB LPDDR5X capacity in real-world agentic AI applications. As Intel has now outlined these architectures at Hot Chips 2026, the focus shifts to the deployment of these high-core-count systems and the continued growth of the R&D operations in Israel as mentioned by calcalistech.com.
