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

Dell R7715 vs HPE DL345 Gen11

A specification-by-specification comparison of the Dell PowerEdge R7715 and the HPE ProLiant DL345 Gen11, built from Dell’s and HPE’s own documents. 5 headline measures favour the R7715 and none favour the DL345 Gen11, and 17 processors appear in both lists.

Bottom line. R7715 leads on virtualisation, databases and in-memory work, storage density, 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 R7715 if…

  • Memory ceiling: 6 TB against 3 TB on the DL345 Gen11
  • Drive bays: 40 against 36 on the DL345 Gen11
  • Accelerators: Up to 6 against Up to 4 on the DL345 Gen11
  • Eight x16 Gen5 slots on one EPYC 9005 socket — twice the four Gen5 slots of the R7615 it succeeds.

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.

07 — Questions

R7715 vs DL345 Gen11, answered

Is the R7715 or the DL345 Gen11 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R7715 lists 18 processors up to 160 cores at 400 W; the DL345 Gen11 lists 40 up to 160 cores at 400 W. Fully populated that is 160 cores against 160.

Which holds more memory?

The R7715 has 24 DIMM slots and a stated ceiling of 6 TB. The DL345 Gen11 has 12 and 3.0 TB.

Which takes more drives?

R7715: 40 bays across 10 documented layouts. DL345 Gen11: 36 across 18. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R7715: up to 6 accelerators, 4 double-wide cards listed. DL345 Gen11: up to 4, 0 double-wide listed.

Do they share any processors?

Yes — 17 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. R7715: Dell PowerEdge R7715 Technical Guide (May 2026) (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.
