Intel Xeon 6520P Processor
Intel Xeon 6520P Processor
The Intel Xeon 6520P is a server/workstation processor with 24 cores, launched in February 2025, at an MSRP of $1295. It is part of the Xeon 6 lineup, using the Granite Rapids-SP architecture with Socket 4710. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 48 threads. To further increase overall system performance, up to two Xeon 6520P CPUs can work together in a multi-processor (SMP) configuration. Xeon 6520P has 144 MB of L3 cache and operates at 2.4 GHz by default, but can boost up to 4 GHz, depending on the workload. Intel is making the Xeon 6520P on a 5 nm production node, the transistor count is unknown. The multiplier is locked on Xeon 6520P, which limits its overclocking potential.
With a TDP of 210 W, the Xeon 6520P is extremely power hungry, which means you need top-notch cooling. Intel’s processor supports DDR5 memory with an eight-channel interface. The highest officially supported memory speed is 6400 MT/s. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, Xeon 6520P uses a PCI-Express Gen 5 connection. This processor lacks integrated graphics, you might need a graphics card.
