Intel · Xeon W · 2024 · LGA4677
The Intel Xeon w5-2555X is a desktop processor with 14 cores, released in 2024 at an MSRP of N/A. 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 28 threads for improved parallelism. The Xeon w5-2555X has a base clock of 3.3 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 210W, the Xeon w5-2555X 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 33.75MB of L3 cache.
