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

Dell R740 vs Dell R740xd

A specification-by-specification comparison of the Dell PowerEdge R740 and the Dell PowerEdge R740xd, built from Dell’s own documents. 1 headline measure favours the R740, 1 favours the R740xd, and 111 processors appear in both lists.

Bottom line. R740xd leads on storage density. 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 R740 if…

  • Largest power supply: 2,600 W against 2,400 W on the R740xd
  • Keeping every drive at the front is the trade that buys room inside: Dell allows this model three double-width 300 W accelerators or six single-width 150 W ones, plus three double-width or four single-width FPGAs, with no drive-chassis condition attached. The R740xd’s equivalent row stops at two cards and ties them to its 24-bay build.

Choose the R740xd if…

  • Drive bays: 24 against 16 on the R740
  • Dell’s specification table gives this chassis three separate rows of drive bays — front, mid-chassis and rear — where the R740 printed in the same document has front bays only.

07 — Questions

R740 vs R740xd, answered

Is the R740 or the R740xd the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R740 lists 111 processors up to 28 cores at 205 W; the R740xd lists 111 up to 28 cores at 205 W. Fully populated that is 56 cores against 56.

Which holds more memory?

The R740 has 24 DIMM slots and a stated ceiling of 3 TB with RDIMM/LRDIMM. The R740xd has 24 and 3 TB with RDIMM/LRDIMM.

Which takes more drives?

R740: 16 bays across 3 documented layouts. R740xd: 24 across 6. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R740: up to 6 accelerators, 2 double-wide cards listed. R740xd: up to 6, 2 double-wide listed.

Do they share any processors?

Yes — 111 processors appear in both documents, including the Intel Xeon Platinum 8280L. That makes a like-for-like build possible on either server.

Where these figures come from. R740: Dell EMC PowerEdge R740 and R740xd Technical Guide (Rev. A12, August 2022) (Dell document). R740xd: Dell EMC PowerEdge R740 and R740xd Technical Guide (Rev. A12, August 2022) (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.
