Intel Xeon W5-2455X 12-Core 3.20GHz FCLGA4677 Workstation Processor
The Intel Xeon W5-2455X is a boxed workstation processor built on the Sapphire Rapids architecture and Intel 7 manufacturing technology, combining 12 performance cores with 24 threads, a 3.20 GHz base frequency, up to 4.60 GHz maximum turbo frequency, and 30 MB of Intel Smart Cache. Its FCLGA4677 socket and Intel W790 chipset platform support four-channel DDR5 memory at up to 4800 MT/s with ECC RDIMMs, so the processor can address the large memory pools that CAD, simulation, and rendering workloads demand.
PCIe 5.0 connectivity with 112 native lanes gives the platform headroom for professional graphics cards, NVMe storage, and networking adapters, while Intel Hyper-Threading, AVX-512, and Advanced Matrix Extensions accelerate compatible technical and AI tasks. The processor carries a 225 W base power rating and 350 W maximum turbo power, so a compatible FCLGA4677 cooling solution and adequate power delivery are required. It is intended for single-socket workstations and does not support dual-processor configurations.
