Xeon Platinum 8460H 40-Core Server Processor

The Intel Xeon Platinum 8460H is a 40-core server processor built on 10 nm Sapphire Rapids architecture. It runs at a 2.2 GHz base frequency with a 3.8 GHz maximum turbo frequency and provides 80 threads through hyper-threading. The LGA 4677 package includes 105 MB of L3 cache and a 330 W thermal design power.

Suited For Dense Virtualisation

This CPU suits deployments that need high core counts and large memory capacity, supporting up to 4 TB across eight DDR5 channels at 4800 MT/s 1DPC or 4400 MT/s 2DPC. PCIe 5.0 delivers 80 lanes for fast I/O. Buyers who need integrated graphics or a lower power envelope should consider other options.

Capacity And Headroom

Eight memory channels give ample bandwidth for in-memory databases and virtualisation hosts, while 40 cores handle heavy parallel tasks. The 330 W TDP demands robust cooling infrastructure. Maximum turbo frequency reaches 3.8 GHz, though sustained all-core speeds will settle lower under full load.

Highlights

  • 40 cores and 80 threads handle heavy parallel workloads
  • 2 GHz base with 3.8 GHz max turbo adapts to burst demands
  • 105 MB L3 cache keeps large datasets close to cores
  • 8-channel DDR5 up to 4800 MT/s feeds memory-hungry applications

Questions about this item

What motherboard socket and power delivery do I need for this LGA 4677 330W processor?

A server board with an LGA 4677 socket and a VRM rated for at least 330W TDP is required; the CPU draws up to 330W under load.

Can I keep my existing DDR5-4800 RDIMMs when moving from a 1DPC to a 2DPC configuration with this Xeon?

Yes, the memory controller runs DDR5 at 4800 MT/s with one DIMM per channel and at 4400 MT/s with two DIMMs per channel across eight channels.

How do I verify the 40 cores and 80 threads are active after installation?

Check the OS task manager or run `lscpu` — it should report 40 cores, 80 threads, a base clock of 2.2 GHz and a max turbo of 3.8 GHz.
