Dell R6715 vs HPE DL320 Gen12
A specification-by-specification comparison of the Dell PowerEdge R6715 and the HPE ProLiant Compute DL320 Gen12, built from Dell’s and HPE’s own documents. 3 headline measures favour the R6715, 2 favour the DL320 Gen12, and they share no processors.
Bottom line. R6715 leads on virtualisation, databases and in-memory work, storage density. DL320 Gen12 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.
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…
- Cores, fully populated: 160 against 144 on the DL320 Gen12
- Memory ceiling: 6 TB against 4 TB on the DL320 Gen12
- Drive bays: 22 against 20 on the DL320 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 DL320 Gen12 if…
- Accelerators: Up to 4 against Up to 3 on the R6715
- Largest power supply: 2,400 W against 1,800 W on the R6715
- 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.

R6715 vs DL320 Gen12, answered
Is the R6715 or the DL320 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 DL320 Gen12 lists 32 up to 144 cores at 350 W. Fully populated that is 160 cores against 144.
Which holds more memory?
The R6715 has 24 DIMM slots and a stated ceiling of 6 TB. The DL320 Gen12 has 16 and 4 TB.
Which takes more drives?
R6715: 22 bays across 8 documented layouts. DL320 Gen12: 20 across 9. 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. 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. R6715: Dell PowerEdge R6715 Technical Guide (June 2026) (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.
