Server CPU for dense compute

The Intel Xeon Gold 6448Y is a 32-core server processor built for two-socket platforms. It targets workloads that scale across many threads, such as virtualisation hosts, database nodes and high-performance computing clusters. Buyers who need single-thread speed above all else or who are building single-socket workstations will not match the design intent.

32 cores and 60 MB L3 cache

The chip runs at a 2.1 GHz base frequency and can reach 4.1 GHz max turbo when thermal headroom allows. Eight DDR5-4800 channels support up to 4 TB of memory, giving ample bandwidth for in-memory datasets. Workloads that exceed 64 threads or require more than 80 PCIe 5.0 lanes will hit the architectural ceiling of this part.

LGA 4677 socket and 225 W TDP

The processor fits the LGA 4677 land-grid array and is manufactured on a 10 nm Sapphire Rapids core. No cooling solution is included, so a server-grade heatsink or liquid loop rated for 225 W must be sourced separately. The 2S scalability limit means the package cannot be used in four-socket or larger topologies.

Questions about this item

Will my existing LGA 4677 cooler handle the 225 W thermal design power of this Xeon Gold 6448Y?

The processor has a 225 W TDP and ships without a cooling device, so you must provide a cooler rated for at least that heat load.

How can I verify the 32 cores and 64 threads are active after installing the Xeon Gold 6448Y?

Check the OS task manager or run lscpu; both should report 32 physical cores and 64 logical processors at the 2.1 GHz base frequency.

Does the box contain DDR5 4800 memory modules or only the Xeon Gold 6448Y processor?

The package includes the processor only; DDR5 4800 memory must be purchased separately to populate the eight memory channels.
