Processor Intel Xeon Silver 4208 2.1GHz 8 Cores LGA 3647

Processor Intel Xeon Silver 4208 2.1GHz 8 Cores LGA 3647 is a server-grade CPU designed for ThinkSystem servers and similar server/workstation platforms. It features 8 physical cores, a base clock of 2.1 GHz and a boost frequency up to 3.2 GHz, supports up to 1 TB of DDR4 memory via a hexa-channel memory architecture, and implements the AVX-512 instruction set for improved compute performance. The processor is compatible with LGA 3647 (Socket P) platforms such as the ThinkSystem ST550.

Advantages

The Intel Xeon Silver 4208 delivers a balance of core count and clock speed suitable for multi-threaded server workloads, offers scalability for dual-socket (2S) systems, and supports high memory capacity and bandwidth through its hexa-channel DDR4 memory design. Its support for AVX-512 expands capabilities for vectorized compute tasks. The chip comes in a compact package size (76 x 56.5 mm) and is tailored for reliability and manageability in business server environments.
