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

Dell R760 vs Dell R770

A specification-by-specification comparison of the Dell PowerEdge R760 and the Dell PowerEdge R770, built from Dell’s own documents. None of the headline measures favour the R760; 3 favour the R770, and they share no processors.

Bottom line. R770 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 R760 if…

  • Dell documents 51 processor SKUs, 31 drive-bay layouts and 10 power supplies for this one chassis — far more choice than the R760xs, R760xd2 or R760xa siblings.

Choose the R770 if…

  • Cores, fully populated: 288 against 128 on the R760
  • Drive bays: 44 against 28 on the R760
  • Fastest network option: 400 GbE class against 200 GbE class on the R760
  • Forty front E3.S Gen5 bays plus four at the rear; Dell puts the front alone at 2457.6 TB raw.

07 — Questions

R760 vs R770, answered

Is the R760 or the R770 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R760 lists 51 processors up to 64 cores at 350 W; the R770 lists 23 up to 144 cores at 350 W. Fully populated that is 128 cores against 288.

Which holds more memory?

The R760 has 32 DIMM slots and a stated ceiling of 8 TB. The R770 has 32 and 8 TB.

Which takes more drives?

R760: 28 bays across 30 documented layouts. R770: 44 across 11. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R760: up to 6 accelerators, 9 double-wide cards listed. R770: up to 6, 5 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. R760: Dell PowerEdge R760 Technical Guide (Rev. A06, June 2026) (Dell document). R770: Dell PowerEdge R770 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.
