Dell R6615 vs HPE DL320 Gen11

A specification-by-specification comparison of the Dell PowerEdge R6615 and the HPE ProLiant DL320 Gen11, built from Dell’s and HPE’s own documents. 3 headline measures favour the R6615, 2 favour the DL320 Gen11, and they share no processors.

Bottom line. R6615 leads on virtualisation, databases and in-memory work, storage density. DL320 Gen11 leads on AI and acceleration. 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 R6615 if…

  • Cores, fully populated: 128 against 64 on the DL320 Gen11
  • Memory ceiling: 3 TB against 2.04 TB on the DL320 Gen11
  • Drive bays: 16 against 12 on the DL320 Gen11
  • One socket spans the whole EPYC 9004 range Dell lists here, from 16-core parts to the 128-core 9754, in a single rack unit.

Choose the DL320 Gen11 if…

  • Accelerators: Up to 4 against Up to 2 on the R6615
  • Largest power supply: 2,200 W against 1,800 W on the R6615
  • Four chassis on one platform — 4 LFF, 8+2 SFF, 12 LFF and GPU Dense — so the same model covers a branch file server, a 1U disk shelf or an accelerator node.

07 — Questions

R6615 vs DL320 Gen11, answered

Is the R6615 or the DL320 Gen11 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R6615 lists 23 processors up to 128 cores at 400 W; the DL320 Gen11 lists 46 up to 64 cores at 330 W. Fully populated that is 128 cores against 64.

Which holds more memory?

The R6615 has 12 DIMM slots and a stated ceiling of 3 TB. The DL320 Gen11 has 16 and 2.04 TB.

Which takes more drives?

R6615: 16 bays across 16 documented layouts. DL320 Gen11: 12 across 7. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R6615: up to 2 accelerators, 0 double-wide cards listed. DL320 Gen11: up to 4, 3 double-wide listed.

Do they share any processors?

No. The two documents list different processors, so a like-for-like processor build is not possible across these two.

Where these figures come from. R6615: Dell PowerEdge R6615 Technical Guide (July 2026, Rev. A07) (Dell document). DL320 Gen11: HPE ProLiant DL320 Gen11 QuickSpecs (Version 41 - 03-Aug-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.
