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

Dell R640 vs HPE DL360 Gen12

A specification-by-specification comparison of the Dell PowerEdge R640 and the HPE ProLiant Compute DL360 Gen12, built from Dell’s and HPE’s own documents. None of the headline measures favour the R640; 5 favour the DL360 Gen12, and they share no processors.

Bottom line. DL360 Gen12 leads on virtualisation, databases and in-memory work, 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 R640 if…

  • Slot count does not drop with the rack unit: the 2U members of this generation carry the same 24 DDR4 slots, so a memory-hungry workload costs no extra height here.

Choose the DL360 Gen12 if…

  • Cores, fully populated: 288 against 56 on the R640
  • Memory ceiling: 8 TB against 1.53 TB on the R640
  • Drive bays: 20 against 18 on the R640
  • Twenty E3.S NVMe bays in 1U — five front boxes that each take four E3.S or two U.3 SFF drives, and can be mixed.

07 — Questions

R640 vs DL360 Gen12, answered

Is the R640 or the DL360 Gen12 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R640 lists 70 processors up to 28 cores at 205 W; the DL360 Gen12 lists 33 up to 144 cores at 350 W. Fully populated that is 56 cores against 288.

Which holds more memory?

The R640 has 24 DIMM slots and a stated ceiling of RDIMM 1.53 TB; LRDIMM 3 TB; NVDIMM 192 GB; PMem 6.14 TB. The DL360 Gen12 has 32 and 8.0 TB.

Which takes more drives?

R640: 18 bays across 6 documented layouts. DL360 Gen12: 20 across 5. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R640: up to 3 accelerators, 0 double-wide cards listed. DL360 Gen12: up to 3, 0 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. R640: Dell EMC PowerEdge R640 Technical Guide (Rev. A10, August 2022) (Dell document). DL360 Gen12: HPE ProLiant Compute DL360 Gen12 QuickSpecs (Version 18 - 03-Aug-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.
