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

Dell R7615 vs HPE DL345 Gen11

A specification-by-specification comparison of the Dell PowerEdge R7615 and the HPE ProLiant DL345 Gen11, built from Dell’s and HPE’s own documents. 2 headline measures favour the R7615, 2 favour the DL345 Gen11, and 19 processors appear in both lists.

Bottom line. R7615 leads on AI and acceleration. DL345 Gen11 leads on virtualisation, 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 R7615 if…

  • Accelerators: Up to 6 against Up to 4 on the DL345 Gen11
  • Largest power supply: 2,400 W against 2,200 W on the DL345 Gen11
  • Three double-wide 300 W GPUs from a one-socket server — one more than the two-socket R7625 is rated for.

Choose the DL345 Gen11 if…

  • Cores, fully populated: 160 against 128 on the R7615
  • Fastest network option: 200 GbE class against 100 GbE class on the R7615
  • 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.

07 — Questions

R7615 vs DL345 Gen11, answered

Is the R7615 or the DL345 Gen11 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R7615 lists 23 processors up to 128 cores at 400 W; the DL345 Gen11 lists 40 up to 160 cores at 400 W. Fully populated that is 128 cores against 160.

Which holds more memory?

The R7615 has 12 DIMM slots and a stated ceiling of 3 TB. The DL345 Gen11 has 12 and 3.0 TB.

Which takes more drives?

R7615: 36 bays across 24 documented layouts. DL345 Gen11: 36 across 18. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R7615: up to 6 accelerators, 7 double-wide cards listed. DL345 Gen11: up to 4, 0 double-wide listed.

Do they share any processors?

Yes — 19 processors appear in both documents, including the AMD EPYC 9754. That makes a like-for-like build possible on either server.

Where these figures come from. R7615: Dell PowerEdge R7615 Technical Guide (July 2026, Rev. A07) (Dell document). DL345 Gen11: HPE ProLiant DL345 Gen11 QuickSpecs (Version 40 - August 3, 2026; footer a50004298enw V40 03-August-2026) (HPE document). Each claim on this page is derived from those documents, checked page by page on the two data sheets, and carries no pricing.
