Dell R6615 vs HPE DL320 Gen12

A specification-by-specification comparison of the Dell PowerEdge R6615 and the HPE ProLiant Compute DL320 Gen12, built from Dell’s and HPE’s own documents. None of the headline measures favour the R6615; 6 favour the DL320 Gen12, and they share no processors.

Bottom line. DL320 Gen12 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 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 DL320 Gen12 if…

  • Cores, fully populated: 144 against 128 on the R6615
  • Memory ceiling: 4 TB against 3 TB on the R6615
  • Drive bays: 20 against 16 on the R6615
  • Xeon 6 in a single socket: E-core parts up to 144 cores or P-core parts up to 86, including six Rich I/O processors HPE groups as single-socket parts.

07 — Questions

R6615 vs DL320 Gen12, answered

Is the R6615 or the DL320 Gen12 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 Gen12 lists 32 up to 144 cores at 350 W. Fully populated that is 128 cores against 144.

Which holds more memory?

The R6615 has 12 DIMM slots and a stated ceiling of 3 TB. The DL320 Gen12 has 16 and 4 TB.

Which takes more drives?

R6615: 16 bays across 16 documented layouts. DL320 Gen12: 20 across 9. 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 Gen12: up to 4, 0 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 Gen12: HPE ProLiant Compute DL320 Gen12 QuickSpecs (Version 20 - 08-Sep-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.
