32-Core Xeon Gold 6438N for dual-socket servers
The Intel Xeon Gold 6438N is a 32-core, 64-thread server processor built on 10 nm Sapphire Rapids architecture. It operates at a 2.0 GHz base frequency with a 3.6 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. It is intended for dual-socket platforms that require high core counts and large memory capacity.
Suited for memory-heavy workloads.
This processor supports eight-channel DDR5 4800 memory up to 4 TB and provides 80 PCI Express 5.0 lanes, making it suitable for virtualisation hosts, database servers and compute clusters that benefit from high memory bandwidth and multi-socket scaling. Buyers building single-socket systems or needing lower power consumption should look elsewhere, as the 205 W TDP and 2S scalability target dual-socket deployments.
LGA 4677 socket with 80 PCIe 5.0 lanes decides fit
The single specification that determines compatibility is the LGA 4677 socket paired with 80 lanes of PCI Express 5.0. A motherboard must provide this socket, support the 205 W thermal envelope and deliver eight-channel DDR5 4800 memory to use the processor. Without a platform that matches these requirements the CPU cannot be installed or operated.

Questions about this item
Will the 32-core 2.0 GHz processor require thermal-paste replacement or cooler servicing after extended operation?
The processor ships without a cooler, so maintenance depends on the third-party solution chosen; Intel specifies a 205 W thermal design power for the 10 nm Sapphire Rapids die.
Which limit appears first when all 64 threads run continuously at the 3.6 GHz maximum turbo frequency?
The 205 W thermal design power is the primary ceiling; sustained all-core turbo is constrained by the package power budget and the cooling capacity installed.
How much heat and fan noise should I expect from the 64-thread CPU running all day?
With a 205 W TDP the chip can dissipate significant heat under load; actual noise and temperature depend on the cooler selected for the LGA 4677 socket.
