Intel “Diamond Rapids” Xeon CPU to Feature up to 192 P-Cores and 500 W TDP

Intel’s next-generation “Oak Stream” platform is preparing to accommodate the upcoming “Diamond Rapids” Xeon CPU generation, and we are receiving more interesting details about the top-end configurations Intel will offer. According to the HEPiX TechWatch working group, the Diamond Rapids Intel Xeon 7 will feature up to 192 P-cores in the top-end SKU, split across four 48-core tiles. Intel has dedicated two primary SKU separators, where some models use eight-channel DDR5 memory, and the top SKUs will arrive with 16-channel DDR5 memory. Using MRDIMM Gen 2 for memory will enable Intel to push transfer rates to 12,800 MT/s per DIMM, providing massive bandwidth across 16 channels and keeping the “Panther Cove” cores busy with sufficient data. Intel planned the SoC to reach up to 500 W in a single socket.

As the first mass-produced 18A node product, Diamond Rapids will be the first to support Intel’s APX, also featuring numerous improvements to the efficiency of AMX. Intel also plans to embed native support for more floating-point number formats, such as NVIDIA’s TF32, and lower-precision FP8. As most of the world’s inference is good enough to run on a CPU, Intel aims to accelerate basic inference operations for smaller models, enabling power users to run advanced workloads on CPUs alone. With a 1S, 2S, and 4S LGA 9324 configuration, Diamond Rapids will offer 768 cores in a single server rack, with a power usage of only 2000 W. Supporting external accelerators will be provided via the PCIe Gen 6 connector. Scheduled for arrival in 2026, Intel will likely time the launch to coincide with its upcoming “Jaguar Shores” AI accelerators, making a perfect pair for a complete AI system.
