Intel Xeon Platinum 8468 server processor PK8071305072501 48-core 2.1 GHz 350W

SKU CH-4JKY-A4TGA MPN PK8071305072501

48-core server CPU with 96 threads, 105 MB L3 cache, DDR5-4800 support up to 4 TB, 80 PCIe 5.0 lanes, 350 W TDP

  • NameXeon Platinum 8468
  • CPU Socket TypeLGA 4677
  • Core NameSapphire Rapids
  • # of Cores48-Core
  • # of Threads96
  • Operating Frequency2.1 GHz
  • 48 cores and 96 threads handle heavy parallel workloads
  • Max turbo frequency reaches 3.80 GHz for burst performance
  • 105 MB L3 cache reduces latency for large datasets
  • Eight-channel DDR5 controller supports up to 4 TB memory capacity
  • PCIe 5.0 with 80 lanes delivers high-speed I/O throughput

Target workloads

The Intel Xeon Platinum 8468 is a 48-core server processor built for dual-socket platforms that need high thread density. It addresses virtualisation hosts, large-scale databases and compute clusters where 96 threads and 105 MB of L3 cache reduce scheduling pressure. Buyers needing single-socket density beyond this core count or specialised accelerator integration will not find those capabilities here.

Memory and I/O headroom

The integrated controller runs DDR5 at up to 4800 MT/s with one DIMM per channel and 4400 MT/s with two, across eight channels for a 4 TB maximum capacity. Eighty PCI Express 5.0 lanes provide connectivity for storage arrays, high-speed networking or GPU attachments without lane-starvation. Systems requiring more than eight memory channels or CXL-attached memory tiers fall outside this design.

Thermal and scaling limits

A 350 W thermal design power demands robust cooling infrastructure; no cooling device is included. The processor scales to two sockets, offering a practical ceiling for workloads that fit within that envelope. Deployments targeting four-socket scale-up, liquid-cooled overclocking beyond 3.80 GHz max turbo, or lower-power density targets should evaluate alternative SKUs.

Questions about this item

What cooling solution does the 350 W Xeon Platinum 8468 require since none is included?

The processor is sold without a cooling device; a compatible LGA 4677 heatsink or liquid cooler rated for at least 350 W TDP must be sourced separately.

Which limit appears first when all 48 cores sustain heavy workloads on the Xeon Platinum 8468?

The 350 W thermal design power is the primary constraint; the CPU will throttle clocks to stay within that envelope before other limits are reached.

How loud and hot does the Xeon Platinum 8468 get when running continuously at full load?

Noise and temperature depend entirely on the aftermarket cooler chosen; the 350 W TDP means a high-capacity server heatsink or liquid loop is needed to keep thermals and acoustics acceptable.
