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

Dell R6615 vs HPE DL325 Gen11

A specification-by-specification comparison of the Dell PowerEdge R6615 and the HPE ProLiant DL325 Gen11, built from Dell’s and HPE’s own documents. None of the headline measures favour the R6615; 5 favour the DL325 Gen11, and 19 processors appear in both lists.

Bottom line. DL325 Gen11 leads on virtualisation, 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 R6615 if…

  • 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 DL325 Gen11 if…

  • Cores, fully populated: 160 against 128 on the R6615
  • Drive bays: 20 against 16 on the R6615
  • Accelerators: Up to 4 against Up to 2 on the R6615
  • 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.

07 — Questions

R6615 vs DL325 Gen11, answered

Is the R6615 or the DL325 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 DL325 Gen11 lists 40 up to 160 cores at 400 W. Fully populated that is 128 cores against 160.

Which holds more memory?

The R6615 has 12 DIMM slots and a stated ceiling of 3 TB. The DL325 Gen11 has 12 and 3.0 TB.

Which takes more drives?

R6615: 16 bays across 16 documented layouts. DL325 Gen11: 20 across 8. 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. DL325 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. R6615: Dell PowerEdge R6615 Technical Guide (July 2026, Rev. A07) (Dell document). DL325 Gen11: HPE ProLiant DL325 Gen11 QuickSpecs (Version 40 - 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.
