Dell R570 vs HPE DL340e Gen12
A specification-by-specification comparison of the Dell PowerEdge R570 and the HPE ProLiant Compute DL340e Gen12, built from Dell’s and HPE’s own documents. 2 headline measures favour the R570, 3 favour the DL340e Gen12, and 22 processors appear in both lists.
Bottom line. R570 leads on virtualisation, databases and in-memory work, AI and acceleration. DL340e 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.
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…
- Memory ceiling: 4 TB against 2 TB on the DL340e Gen12
- Accelerators: Up to 4 against None listed on the DL340e Gen12
- 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 DL340e Gen12 if…
- Drive bays: 34 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
- Up to 24 × 3.5-inch SAS/SATA bays in 2U, and HPE’s capacity table fills them with 26 TB disks for 624 TB raw.

R570 vs DL340e Gen12, answered
Is the R570 or the DL340e 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 DL340e Gen12 lists 30 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 DL340e Gen12 has 16 and 2TB.
Which takes more drives?
R570: 32 bays across 13 documented layouts. DL340e Gen12: 34 across 3. 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. DL340e Gen12: no accelerator option in its document.
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). DL340e Gen12: HPE ProLiant Compute DL340e Gen12 QuickSpecs (Version 5 - August 3, 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.
