Dell R770 vs HPE DL380 Gen12

A specification-by-specification comparison of the Dell PowerEdge R770 and the HPE ProLiant Compute DL380 Gen12, built from Dell’s and HPE’s own documents. 2 headline measures favour the R770, 1 favours the DL380 Gen12, and 23 processors appear in both lists.

Bottom line. R770 leads on storage density. DL380 Gen12 leads on AI and acceleration. 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…

  • Drive bays: 44 against 36 on the DL380 Gen12
  • Largest power supply: 3,200 W against 2,200 W on the DL380 Gen12
  • Forty front E3.S Gen5 bays plus four at the rear; Dell puts the front alone at 2457.6 TB raw.

Choose the DL380 Gen12 if…

  • Accelerators: Up to 8 against Up to 6 on the R770
  • Two Xeon 6 core types in one chassis: seven E-core parts of 64 to 144 cores for dense throughput, and 27 P-core parts of 8 to 86 cores for per-core speed.

07 — Questions

R770 vs DL380 Gen12, answered

Is the R770 or the DL380 Gen12 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 DL380 Gen12 lists 34 up to 144 cores at 350 W. Fully populated that is 288 cores against 288.

Which holds more memory?

The R770 has 32 DIMM slots and a stated ceiling of 8 TB. The DL380 Gen12 has 32 and 8.0 TB.

Which takes more drives?

R770: 44 bays across 11 documented layouts. DL380 Gen12: 36 across 13. 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. DL380 Gen12: up to 8, 4 double-wide listed.

Do they share any processors?

Yes — 23 processors appear in both documents, including the Intel Xeon 6 6780E. That makes a like-for-like build possible on either server.

Where these figures come from. R770: Dell PowerEdge R770 Technical Guide (May 2026) (Dell document). DL380 Gen12: HPE ProLiant DL380 Gen12 QuickSpecs (Version 19 - 08-Sep-2026) (HPE document). Each claim on this page is derived from those documents, checked page by page on the two data sheets, and carries no pricing.
