32-core Xeon for dual-socket servers

This Intel Xeon Gold 6438Y+ is a 32-core server processor built on a 10 nm process. It targets dual-socket platforms that need high thread density for virtualisation, database or high-performance computing workloads. The chip fits the LGA 4677 socket and delivers 64 threads for parallel tasks. It is not for single-socket workstations or builds that cannot accommodate a 205 W thermal envelope.

60 MB L3 cache and DDR5-4800 across eight channels

The processor provides 60 MB of shared L3 cache to keep large working sets close to the cores. Eight memory channels support DDR5 at 4800 MT/s, giving substantial bandwidth for memory-bound applications. Maximum addressable capacity reaches 4 TB per socket, so very large in-memory datasets fit comfortably. Workloads that exceed 80 PCIe 5.0 lanes or require more than two sockets will hit platform limits.

LGA 4677 socket with 80 lanes of PCIe 5.0

Installation requires an LGA 4677 motherboard designed for 205 W cooling and eight-channel memory routing. The 80 PCI Express 5.0 lanes connect directly to the CPU, freeing the chipset for storage and networking add-in cards. Dual-socket scalability is native, so a second identical processor doubles cores, memory channels and I/O without extra bridges. Systems limited to fewer memory slots or a single socket cannot use the full capability.

Perguntas sobre este artigo

Will the Xeon Gold 6438Y+ fit in my existing LGA 4677 motherboard and work with DDR5 4800 memory I already own?

Yes, the processor uses the LGA 4677 socket and its integrated memory controller is rated for DDR5 4800, so it will install in a compatible board and run that memory speed.

How can I verify the 32 cores and 64 threads are active after installation?

Check the operating system task manager or run lscpu; both will show 32 cores and 64 threads running at the 2.0 GHz base frequency.

Does the box include a cooler or thermal paste, or must I buy them separately?

The processor is sold as a tray unit without a cooler or thermal paste; a compatible LGA 4677 heatsink and thermal compound must be purchased separately.
