Dell R570 vs HPE DL340 Gen12

A specification-by-specification comparison of the Dell PowerEdge R570 and the HPE ProLiant Compute DL340 Gen12, built from Dell’s and HPE’s own documents. None of the headline measures favour the R570; 3 favour the DL340 Gen12, and 22 processors appear in both lists.

Bottom line. DL340 Gen12 leads on 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 R570 if…

  • Three processor types for one socket: seven E-core parts up to 144 cores, ten standard P-core parts up to 86 cores, and six R1S P-core parts carrying 136 PCIe 5.0 lanes.

Choose the DL340 Gen12 if…

  • Drive bays: 36 against 32 on the R570
  • Largest power supply: 3,200 W against 1,800 W on the R570
  • Fastest network option: 400 GbE class against 200 GbE class on the R570
  • Three factory chassis on one single-socket platform: SFF for up to 24 × 2.5-inch or 36 × E3.S drives, LFF for 12 × 3.5-inch, and a Front GPU model that HPE documents with four double-wide accelerators.

07 — Questions

R570 vs DL340 Gen12, answered

Is the R570 or the DL340 Gen12 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R570 lists 23 processors up to 144 cores at 350 W; the DL340 Gen12 lists 33 up to 144 cores at 350 W. Fully populated that is 144 cores against 144.

Which holds more memory?

The R570 has 16 DIMM slots and a stated ceiling of 4 TB. The DL340 Gen12 has 16 and 4TB.

Which takes more drives?

R570: 32 bays across 13 documented layouts. DL340 Gen12: 36 across 7. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R570: up to 4 accelerators, 2 double-wide cards listed. DL340 Gen12: up to 4, 0 double-wide listed.

Do they share any processors?

Yes — 22 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. R570: Dell PowerEdge R570 Technical Guide (December 2025) (Dell document). DL340 Gen12: HPE ProLiant Compute DL340 Gen12 QuickSpecs (Version 15 - 08-September-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.
