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

HPE DL345 Gen11 vs HPE DL345 Gen12

A specification-by-specification comparison of the HPE ProLiant DL345 Gen11 and the HPE ProLiant Compute DL345 Gen12, built from HPE’s own documents. None of the headline measures favour the DL345 Gen11; 5 favour the DL345 Gen12, and 21 processors appear in both lists.

Bottom line. DL345 Gen12 leads on virtualisation, databases and in-memory work, AI and acceleration, 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 DL345 Gen11 if…

  • A 2U drive envelope behind one processor: 34 SFF, 20 LFF or 36 E3.S bays, because HPE adds mid-tray and rear cages to the front drive boxes.

Choose the DL345 Gen12 if…

  • Cores, fully populated: 192 against 160 on the DL345 Gen11
  • Memory ceiling: 6 TB against 3 TB on the DL345 Gen11
  • Accelerators: Up to 6 against Up to 4 on the DL345 Gen11
  • Up to 192 cores behind a single socket, with the 500 W EPYC 9965 and 9755 on HPE’s list.

07 — Questions

DL345 Gen11 vs DL345 Gen12, answered

Is the DL345 Gen11 or the DL345 Gen12 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The DL345 Gen11 lists 40 processors up to 160 cores at 400 W; the DL345 Gen12 lists 23 up to 192 cores at 500 W. Fully populated that is 160 cores against 192.

Which holds more memory?

The DL345 Gen11 has 12 DIMM slots and a stated ceiling of 3.0 TB. The DL345 Gen12 has 24 and 6.0 TB.

Which takes more drives?

DL345 Gen11: 36 bays across 18 documented layouts. DL345 Gen12: 36 across 8. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

DL345 Gen11: up to 4 accelerators, 0 double-wide cards listed. DL345 Gen12: up to 6, 2 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.
