Head-to-head · every figure from the vendor documents

Dell R7615 vs Dell R7715

A specification-by-specification comparison of the Dell PowerEdge R7615 and the Dell PowerEdge R7715, built from Dell’s own documents. None of the headline measures favour the R7615; 5 favour the R7715, and they share no processors.

Bottom line. R7715 leads on virtualisation, databases and in-memory work, 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.

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…

  • Three double-wide 300 W GPUs from a one-socket server — one more than the two-socket R7625 is rated for.

Choose the R7715 if…

  • Cores, fully populated: 160 against 128 on the R7615
  • Memory ceiling: 6 TB against 3 TB on the R7615
  • Drive bays: 40 against 36 on the R7615
  • Eight x16 Gen5 slots on one EPYC 9005 socket — twice the four Gen5 slots of the R7615 it succeeds.

07 — Questions

R7615 vs R7715, answered

Is the R7615 or the R7715 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 R7715 lists 18 up to 160 cores at 400 W. Fully populated that is 128 cores against 160.

Which holds more memory?

The R7615 has 12 DIMM slots and a stated ceiling of 3 TB. The R7715 has 24 and 6 TB.

Which takes more drives?

R7615: 36 bays across 24 documented layouts. R7715: 40 across 10. 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. R7715: up to 6, 4 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). R7715: Dell PowerEdge R7715 Technical Guide (May 2026) (Dell document). Each claim on this page is derived from those documents, checked page by page on the two data sheets, and carries no pricing.
