Dell R6715 vs HPE DL325 Gen12

A specification-by-specification comparison of the Dell PowerEdge R6715 and the HPE ProLiant Compute DL325 Gen12, built from Dell’s and HPE’s own documents. 1 headline measure favours the R6715, 3 favour the DL325 Gen12, and 17 processors appear in both lists.

Bottom line. R6715 leads on storage density. DL325 Gen12 leads on virtualisation, 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 R6715 if…

  • Drive bays: 22 against 20 on the DL325 Gen12
  • One socket reaches 160 Zen 5 cores with the EPYC 9845; Dell’s 18-processor list starts at the 8-core, 125 W EPYC 9015 and tops out at 400 W.

Choose the DL325 Gen12 if…

  • Cores, fully populated: 192 against 160 on the R6715
  • Accelerators: Up to 4 against Up to 3 on the R6715
  • Largest power supply: 2,400 W against 1,800 W on the R6715
  • Twice the DIMM slots of the DL325 Gen11 in the same 1U height: 24 slots at two per channel take one socket to 6 TB with 256 GB kits.

07 — Questions

R6715 vs DL325 Gen12, answered

Is the R6715 or the DL325 Gen12 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R6715 lists 18 processors up to 160 cores at 400 W; the DL325 Gen12 lists 23 up to 192 cores at 500 W. Fully populated that is 160 cores against 192.

Which holds more memory?

The R6715 has 24 DIMM slots and a stated ceiling of 6 TB. The DL325 Gen12 has 24 and 6 TB.

Which takes more drives?

R6715: 22 bays across 8 documented layouts. DL325 Gen12: 20 across 6. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R6715: up to 3 accelerators, 0 double-wide cards listed. DL325 Gen12: 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. R6715: Dell PowerEdge R6715 Technical Guide (June 2026) (Dell document). DL325 Gen12: HPE ProLiant Compute DL325 Gen12 QuickSpecs (Version 12 - 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.
