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

Dell R7725 vs Dell R7725xd

A specification-by-specification comparison of the Dell PowerEdge R7725 and the Dell PowerEdge R7725xd, built from Dell’s own documents. 3 headline measures favour the R7725 and none favour the R7725xd, and 19 processors appear in both lists.

Bottom line. R7725 leads on virtualisation, databases and in-memory work, AI and acceleration, 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 R7725 if…

  • Memory ceiling: 6 TB against 3 TB on the R7725xd
  • Accelerators: Up to 6 against None listed on the R7725xd
  • Fastest network option: 200 GbE class against 10 GbE class on the R7725xd
  • 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.

Choose the R7725xd if…

  • All-NVMe by design: 24 U.2 Gen5 bays at x4 each, or a 40-bay E3.S/E3.L front that Dell’s spec sheet rates at up to 9.8 PB.

07 — Questions

R7725 vs R7725xd, answered

Is the R7725 or the R7725xd the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R7725 lists 20 processors up to 192 cores at 500 W; the R7725xd lists 19 up to 192 cores at 500 W. Fully populated that is 384 cores against 384.

Which holds more memory?

The R7725 has 24 DIMM slots and a stated ceiling of 6 TB. The R7725xd has 24 and 3 TB.

Which takes more drives?

R7725: 40 bays across 9 documented layouts. R7725xd: 40 across 2. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R7725: up to 6 accelerators, 6 double-wide cards listed. R7725xd: no accelerator option in its document.

Do they share any processors?

Yes — 19 processors appear in both documents, including the AMD EPYC 9965. That makes a like-for-like build possible on either server.

Where these figures come from. R7725: Dell PowerEdge R7725 Technical Guide (June 2026) (Dell document). R7725xd: Dell PowerEdge R7725xd 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.
