Dell R7615 vs HPE DL340 Gen12

A specification-by-specification comparison of the Dell PowerEdge R7615 and the HPE ProLiant Compute DL340 Gen12, built from Dell’s and HPE’s own documents. 1 headline measure favours the R7615, 4 favour the DL340 Gen12, and they share no processors.

Bottom line. R7615 leads on AI and acceleration. DL340 Gen12 leads on virtualisation, databases and in-memory work, 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 R7615 if…

  • Accelerators: Up to 6 against Up to 4 on the DL340 Gen12
  • Three double-wide 300 W GPUs from a one-socket server — one more than the two-socket R7625 is rated for.

Choose the DL340 Gen12 if…

  • Cores, fully populated: 144 against 128 on the R7615
  • Memory ceiling: 4 TB against 3 TB on the R7615
  • Largest power supply: 3,200 W against 2,400 W on the R7615
  • Three factory chassis on one single-socket platform: SFF for up to 24 × 2.5-inch or 36 × E3.S drives, LFF for 12 × 3.5-inch, and a Front GPU model that HPE documents with four double-wide accelerators.

07 — Questions

R7615 vs DL340 Gen12, answered

Is the R7615 or the DL340 Gen12 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R7615 lists 23 processors up to 128 cores at 400 W; the DL340 Gen12 lists 33 up to 144 cores at 350 W. Fully populated that is 128 cores against 144.

Which holds more memory?

The R7615 has 12 DIMM slots and a stated ceiling of 3 TB. The DL340 Gen12 has 16 and 4TB.

Which takes more drives?

R7615: 36 bays across 24 documented layouts. DL340 Gen12: 36 across 7. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R7615: up to 6 accelerators, 7 double-wide cards listed. DL340 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. R7615: Dell PowerEdge R7615 Technical Guide (July 2026, Rev. A07) (Dell document). DL340 Gen12: HPE ProLiant Compute DL340 Gen12 QuickSpecs (Version 15 - 08-September-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.
