Intel is gearing up for a major leap in server processing power with the 2026 launch of its Oak Stream Xeon platform, centered on the new Diamond Rapids CPUs. Built on the advanced 18A process and featuring the latest Panther Cove cores, Diamond Rapids will serve data centers and high-performance workloads, offering unprecedented compute density. The flagship version will pack four compute tiles per socket, each containing 48 performance cores, yielding a total of 192 cores per CPU socket. With quad-socket server support, a single rack could potentially deliver 768 cores, all while demanding up to 2000W of power for fully loaded configurations.
Reflecting its next-gen ambitions, Diamond Rapids will introduce a new socket type (LGA 9324) and fully embrace cutting-edge connectivity, including PCIe 6.0 and CXL 3, to interface with accelerators and ultra-fast storage. Memory bandwidth is another highlight, as each CPU can handle up to 16 channels of DDR5 with MRDIMM modules at 12800MT/s. For deployments prioritizing efficiency or lower core counts, a trimmed-down model with fewer compute tiles and a single I/O module will also be available, offering reduced memory bandwidth and core capacity for power- or space-constrained scenarios.
Targeting more than just brute force compute, Intel has positioned Diamond Rapids as a CPU primed for Artificial Intelligence inference workloads—especially smaller models that don´t require the raw power of GPUs. Native support for modern numerical formats such as FP8 and TF32, paired with enhancements like Intel APX and an upgraded AMX engine, are designed to make CPUs more competitive for next-gen server tasks in inference and data processing. Diamond Rapids is expected to debut alongside Intel´s Jaguar Shores Artificial Intelligence accelerator, underlining the company’s push for a complete Artificial Intelligence-ready server ecosystem. Formal pricing and direct benchmarks against competitors like AMD´s offerings are still to be announced, but the stage is set for a new chapter in server architecture.
