Xeon Gold 6438M 32-core server processor
The Intel Xeon Gold 6438M is a 32-core, 64-thread server processor built on 10 nm Sapphire Rapids architecture. It operates at a 2.2 GHz base frequency with a 3.9 GHz maximum turbo frequency and includes 60 MB of L3 cache. The CPU fits the LGA 4677 socket and has a 205 W thermal design power.
Suited for dual-socket DDR5 platforms needing 80
This processor supports up to 4 TB of DDR5-4800 memory across eight channels and scales to two sockets, making it appropriate for memory-intensive workloads and high I/O throughput. Builders targeting single-socket boards, lower core counts, or platforms limited to fewer memory channels or PCIe lanes should consider other options.
LGA 4677 socket and 205 W TDP define platform
The processor requires a motherboard with the LGA 4677 socket and cooling capable of dissipating 205 W. Memory must be DDR5-4800, and the platform must deliver eight memory channels and up to 80 PCIe 5.0 lanes to utilise the full specification.

商品問答
How does the 2.2 GHz base clock behave once the Xeon Gold 6438M is installed in a dual-socket server?
The processor runs at 2.2 GHz across all 32 cores under sustained load and can lift individual cores to 3.9 GHz when thermal headroom allows.
What does the PCIe 5.0 interface with 80 lanes cap in real-world I/O?
The 80 lanes of PCIe 5.0 provide up to 32 GT/s per lane for accelerators, storage controllers and networking cards.
What physical clearance does the LGA 4677 socket and 205 W TDP demand in the chassis?
The FCLGA4677 package requires a compatible server board and a cooler rated for at least 205 W of heat dissipation.
