Intel Xeon W5-2455X server processor PK8071305127200

Intel Xeon W5-2455X 12-Core Server Processor

This Intel Xeon W5-2455X is a 12-core, 24-thread server processor built for the LGA 4677 socket. It operates at a base frequency of 3.2 GHz and reaches a maximum turbo frequency of 4.60 GHz with Intel Turbo Boost Max Technology 3.0. The chip provides 30 MB of L3 cache, quad-channel DDR5-4800 memory support up to 2 TB, and 64 lanes of PCI Express 5.0 connectivity. It is manufactured on a 7 nm process with a base power of 200 W and a maximum turbo power of 240 W.

Suited for workstations needing high core counts

This processor suits professionals running multi-threaded workloads such as rendering, simulation, or virtualization that benefit from 12 cores, 24 threads, and quad-channel DDR5 memory. The 64 PCIe 5.0 lanes support high-speed storage and accelerator cards. Buyers who need fewer cores, lower power draw, or compatibility with older motherboards should look at alternative products. Systems must provide cooling capable of handling up to 240 W turbo power and a motherboard with the LGA 4677 socket.

LGA 4677 socket requirement

The single specification that decides fit is the CPU socket type: this processor only installs in an LGA 4677 socket. No other socket will accept it. Verify that your motherboard explicitly lists LGA 4677 support before purchase.
