Intel PK8071305120201 Xeon Silver 4416+ server processor 20-core 2.0 GHz 165W

Server processor for two-socket systems

The Intel Xeon Silver 4416+ is a 20-core, 40-thread CPU built on 10 nm Sapphire Rapids architecture. It runs at a 2.0 GHz base frequency and reaches a 3.9 GHz max turbo frequency with 37.5 MB L3 cache. The part supports 64-bit processing, virtualization technology and Intel AMX, AVX-512 and AVX2 instruction sets for compute-intensive workloads.

Platform and power checks before ordering

The processor requires an LGA 4677 socket and a platform that delivers 165 W thermal design power. Cooling is not included, so a compatible server heatsink must be sourced separately. Memory must be DDR5 4000 operating across eight channels to reach the 4 TB maximum capacity. The system must also provide PCIe 5.0 lanes — up to 80 from this CPU — for high-bandwidth add-in cards or storage.

Build and connectivity implications

As a processor-only unit, the package contains no cooler, mounting hardware or thermal paste. The LGA 4677 land-grid array demands careful alignment during installation to avoid bent contacts. With 2S scalability, two of these CPUs can be paired in a dual-socket board, doubling core count and memory channels while sharing the 80 PCIe 5.0 lanes between sockets for balanced I/O distribution.
