Dell R770 vs Dell R770AP

A specification-by-specification comparison of the Dell PowerEdge R770 and the Dell PowerEdge R770AP, built from Dell’s own documents. 5 headline measures favour the R770 and none favour the R770AP, and they share no processors.

Bottom line. R770 leads on virtualisation, databases and in-memory work, storage density, 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 R770 if…

  • Cores, fully populated: 288 against 256 on the R770AP
  • Memory ceiling: 8 TB against 3 TB on the R770AP
  • Drive bays: 44 against 32 on the R770AP
  • Forty front E3.S Gen5 bays plus four at the rear; Dell puts the front alone at 2457.6 TB raw.

Choose the R770AP if…

  • Up to 128 P-cores and 504 MB of cache per socket, with 72- and 96-core parts for workloads that favour clock speed over core count.

07 — Questions

R770 vs R770AP, answered

Is the R770 or the R770AP the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R770 lists 23 processors up to 144 cores at 350 W; the R770AP lists 5 up to 128 cores at 500 W. Fully populated that is 288 cores against 256.

Which holds more memory?

The R770 has 32 DIMM slots and a stated ceiling of 8 TB. The R770AP has 24 and 3 TB.

Which takes more drives?

R770: 44 bays across 11 documented layouts. R770AP: 32 across 4. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R770: up to 6 accelerators, 5 double-wide cards listed. R770AP: no accelerator option in its document.

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. R770: Dell PowerEdge R770 Technical Guide (May 2026) (Dell document). R770AP: Dell PowerEdge R770AP 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.
