Head-to-head · every figure from the vendor documents

HPE DL325 Gen11 vs HPE DL325 Gen12

A specification-by-specification comparison of the HPE ProLiant DL325 Gen11 and the HPE ProLiant Compute DL325 Gen12, built from HPE’s own documents. None of the headline measures favour the DL325 Gen11; 4 favour the DL325 Gen12, and 21 processors appear in both lists.

Bottom line. DL325 Gen12 leads on virtualisation, databases and in-memory work, network throughput. Neither vendor publishes benchmarks for these machines, so every call here is made on what their documents state.

The measures that decide it

Each row is a figure both vendors publish. Bars show the split between the two; a badge marks the larger figure, which is not always the better buy — a shallower chassis or a lower power ceiling can matter more.

02 — Verdict

Which one, and why

Drawn from the measures above and each model’s own data sheet. Neither vendor publishes benchmark results for these servers, so nothing here claims one is “faster”.

Choose the DL325 Gen11 if…

  • Both EPYC generations in one chassis: HPE’s tables list 21 5th Gen and 19 4th Gen processors, from the 8-core 9015 to the 160-core 9845, including the 9684X with 1,150 MB of L3.

Choose the DL325 Gen12 if…

  • Cores, fully populated: 192 against 160 on the DL325 Gen11
  • Memory ceiling: 6 TB against 3 TB on the DL325 Gen11
  • Largest power supply: 2,400 W against 2,200 W on the DL325 Gen11
  • Twice the DIMM slots of the DL325 Gen11 in the same 1U height: 24 slots at two per channel take one socket to 6 TB with 256 GB kits.

07 — Questions

DL325 Gen11 vs DL325 Gen12, answered

Is the DL325 Gen11 or the DL325 Gen12 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The DL325 Gen11 lists 40 processors up to 160 cores at 400 W; the DL325 Gen12 lists 23 up to 192 cores at 500 W. Fully populated that is 160 cores against 192.

Which holds more memory?

The DL325 Gen11 has 12 DIMM slots and a stated ceiling of 3.0 TB. The DL325 Gen12 has 24 and 6 TB.

Which takes more drives?

DL325 Gen11: 20 bays across 8 documented layouts. DL325 Gen12: 20 across 6. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

DL325 Gen11: up to 4 accelerators, 0 double-wide cards listed. DL325 Gen12: up to 4, 0 double-wide listed.

Do they share any processors?

Yes — 21 processors appear in both documents, including the AMD EPYC 9845. That makes a like-for-like build possible on either server.

Where these figures come from. DL325 Gen11: HPE ProLiant DL325 Gen11 QuickSpecs (Version 40 - 03-Aug-2026) (HPE document).
