HPE

HPE Intel Xeon Silver 4509Y 8 Core 2.60GHz LGA-4677 Processor P67090B21

SKU CH-CWP4-K0X42 MPN P67090B21

An 8-core server processor with 16 threads, 2.60 GHz base clock, 4.10 GHz boost and 22.50 MB L3 cache for LGA-4677 platforms

  • CPU socketLGA 4677
  • 8-core design handles parallel workloads with 16 threads
  • 60 GHz base clock scales to 4.10 GHz turbo for burst performance
  • 50 MB L3 cache reduces latency on large datasets
  • DDR5 memory support at 4.40 GHz increases bandwidth for data-intensive tasks
  • 125 W TDP balances compute density with thermal efficiency

HPE Xeon Silver 4509Y 8-Core Server Processor

The HPE Intel Xeon Silver 4509Y is an octa-core server processor built for LGA-4677 platforms. It runs at a 2.60 GHz base frequency with a 4.10 GHz turbo boost and provides 16 threads for parallel workloads. The chip includes 22.50 MB of L3 cache and supports DDR5 memory at 4.40 GHz. It is designed for rack and tower servers requiring 64-bit processing.

Upgrade From Older Silver Or Bronze Parts

This processor replaces earlier-generation Xeon Silver or Bronze CPUs that use the LGA-4677 socket. The jump is worthwhile when workloads need the higher 4.40 GHz memory speed and the 22.50 MB cache for database or virtualization tasks. A 125 W thermal design power means existing cooling infrastructure rated for this envelope can be reused without redesign.

Suited For Density-Optimised Server Builds

The 3.1 inch by 2.2 inch form factor fits standard server trays where space is constrained. Buyers who need more than eight cores or a higher base frequency should evaluate other SKUs. Systems requiring a lower thermal envelope or a different socket type cannot use this processor.

Questions about this item

Will the LGA-4677 socket fit my server board?

The processor uses the LGA-4677 socket. Confirm your motherboard lists this exact socket before purchase.

What is the correct way to seat the processor in the LGA-4677 socket?

Align the notches on the processor with the socket keys, lower it straight down without pressure, then engage the retention lever fully.

When should the thermal interface material be replaced on this 125 W CPU?

Replace the thermal paste whenever the cooler is removed or if temperatures approach the 100 °C thermal limit under load.
