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

Dell R7625 vs Dell R7725

A specification-by-specification comparison of the Dell PowerEdge R7625 and the Dell PowerEdge R7725, built from Dell’s own documents. None of the headline measures favour the R7625; 3 favour the R7725, and they share no processors.

Bottom line. R7725 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.

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 R7625 if…

  • Two sockets and 24 DDR5 slots in 2U, for up to 256 cores and 6 TB — twice the memory of the one-socket R7615 in the same chassis height.

Choose the R7725 if…

  • Cores, fully populated: 384 against 256 on the R7625
  • Drive bays: 40 against 36 on the R7625
  • Fastest network option: 200 GbE class against 100 GbE class on the R7625
  • Up to 192 Zen5 cores per socket, with even the 500 W parts listed for air cooling — the 4th Gen EPYC R7625 in Dell’s comparison table stopped at 128 cores.

07 — Questions

R7625 vs R7725, answered

Is the R7625 or the R7725 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R7625 lists 19 processors up to 128 cores at 400 W; the R7725 lists 20 up to 192 cores at 500 W. Fully populated that is 256 cores against 384.

Which holds more memory?

The R7625 has 24 DIMM slots and a stated ceiling of 6 TB. The R7725 has 24 and 6 TB.

Which takes more drives?

R7625: 36 bays across 23 documented layouts. R7725: 40 across 9. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R7625: up to 6 accelerators, 0 double-wide cards listed. R7725: up to 6, 6 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. R7625: Dell PowerEdge R7625 Technical Guide (July 2026, Rev. A07) (Dell document). R7725: Dell PowerEdge R7725 Technical Guide (June 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.
