HPE

HPE P53702-B21 AMD EPYC 9124 16-core 3.70 GHz server processor

SKU CH-6K3V-V7EYG MPN P53702-B21

16-core AMD EPYC 9124 server processor runs at 3.70 GHz with 32 threads, 64 MB L3 cache, and fits Socket SP5 systems

  • 16 cores and 32 threads handle parallel workloads
  • 70 GHz boost frequency accelerates single-thread tasks
  • 64 MB L3 cache reduces memory latency
  • SP5 socket fits supported ProLiant Gen11 servers
  • 200 W TDP sets clear thermal envelope

Product identity

This HPE P53702-B21 server processor is an AMD EPYC 9124 with 16 cores and 32 threads, running at a 3 GHz base frequency and a 3.70 GHz boost speed. It fits the SP5 socket and carries 64 MB of L3 cache within a 200 W thermal envelope.

Who this suits

It suits administrators upgrading ProLiant DL325 Gen11, DL345 Gen11 or DL385 Gen11 servers with a supported fourth-generation EPYC CPU. Buyers whose platforms use a different socket or an earlier server generation cannot install this processor.

Deciding specification

The SP5 socket requirement is the single specification that decides fitment; only systems designed for this socket and qualified for the EPYC 9004 series will accept the part.

Questions about this item

Should I choose the 16-core EPYC 9124 or a higher-core-count model from the 9004 series?

The 9124 gives you 16 cores and 32 threads at a 200 W TDP. If your workloads scale across many threads and the server chassis can cool 200 W, a higher-core model will finish those jobs faster; if you run lighter or bursty workloads, the 9124 leaves more thermal headroom for other components.

What does the 3.70 GHz overclocking speed deliver in a real server?

It is the maximum single-core boost clock. When only a few threads are active the processor can reach 3.70 GHz, giving snappier response for latency-sensitive tasks; sustained all-core speeds will be lower and depend on the system cooling and power budget.

How does the SP5 socket limit what I can install?

The SP5 socket is exclusive to AMD EPYC 9004 series processors. You cannot fit earlier EPYC generations or any non-EPYC CPU in this socket, so future upgrades must also be SP5-compatible 9004-series parts.
