Intel · Xeon W · 2024 · LGA4677
The Intel Xeon w9-3575X is a desktop processor with 44 cores, released in 2024 at an MSRP of $3,789. It is part of the Xeon W lineup, using the Xeon W platform, and fits the LGA4677 socket. Internally, it is built on the "Sapphire Rapids" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 88 threads for improved parallelism. The Xeon w9-3575X has a base clock of 2.2 GHz and can boost up to 4.8 GHz depending on workload and thermal headroom. Intel manufactures the "Sapphire Rapids" silicon on a Intel 7 process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR5 memory. With a TDP of 340W, the Xeon w9-3575X runs hot and requires a capable cooling setup. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 97.5MB of L3 cache — an unusually large L3 that greatly benefits latency-sensitive workloads like gaming.
