Dell R6625 vs HPE DL365 Gen11
A specification-by-specification comparison of the Dell PowerEdge R6625 and the HPE ProLiant DL365 Gen11, built from Dell’s and HPE’s own documents. None of the headline measures favour the R6625; 4 favour the DL365 Gen11, and 19 processors appear in both lists.
Bottom line. DL365 Gen11 leads on virtualisation, storage density, 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.
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 R6625 if…
- Two sockets in one rack unit: a pair of 128-core 9754s gives 256 cores, and Dell rates them for air at 30°C with the 8 × 2.5-inch NVMe front or no backplane.
Choose the DL365 Gen11 if…
- Cores, fully populated: 320 against 256 on the R6625
- Drive bays: 20 against 16 on the R6625
- Largest power supply: 2,200 W against 1,800 W on the R6625
- Two EPYC sockets in one rack unit: up to 320 cores and 24 DDR5 slots (6 TB), with 160 PCIe 5.0 lanes across the pair.

R6625 vs DL365 Gen11, answered
Is the R6625 or the DL365 Gen11 the faster server?
Neither document publishes benchmark results, so this page compares what they do state. The R6625 lists 19 processors up to 128 cores at 360 W; the DL365 Gen11 lists 40 up to 160 cores at 400 W. Fully populated that is 256 cores against 320.
Which holds more memory?
The R6625 has 24 DIMM slots and a stated ceiling of 6 TB. The DL365 Gen11 has 24 and 6.0 TB.
Which takes more drives?
R6625: 16 bays across 14 documented layouts. DL365 Gen11: 20 across 7. Counts include rear and mid-chassis positions where the vendor documents them.
Can either take GPUs?
R6625: up to 2 accelerators, 0 double-wide cards listed. DL365 Gen11: up to 2, 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. R6625: Dell PowerEdge R6625 Technical Guide (July 2026, Rev. A07) (Dell document). DL365 Gen11: HPE ProLiant DL365 Gen11 QuickSpecs (Version 45 - 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.
