HPE DL360 Gen12 vs Lenovo SR645 V3

A specification-by-specification comparison of the HPE ProLiant Compute DL360 Gen12 and the Lenovo ThinkSystem SR645 V3, built from HPE’s and Lenovo’s own documents. 4 headline measures favour the DL360 Gen12, 2 favour the SR645 V3, and they share no processors.

Bottom line. DL360 Gen12 leads on virtualisation, databases and in-memory work, storage density, network throughput. SR645 V3 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 DL360 Gen12 if…

  • Memory ceiling: 8 TB against 6 TB on the SR645 V3
  • Drive bays: 20 against 16 on the SR645 V3
  • Largest power supply: 2,200 W against 1,800 W on the SR645 V3
  • 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.

Choose the SR645 V3 if…

  • Cores, fully populated: 320 against 288 on the DL360 Gen12
  • Accelerators: Up to 5 against Up to 3 on the DL360 Gen12
  • Two EPYC sockets in one rack unit: a pair of 160-core 9845s gives 320 cores, and each processor drives its own 12 DDR5 channels.

07 — Questions

DL360 Gen12 vs SR645 V3, answered

Is the DL360 Gen12 or the SR645 V3 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The DL360 Gen12 lists 33 processors up to 144 cores at 350 W; the SR645 V3 lists 46 up to 160 cores at 400 W. Fully populated that is 288 cores against 320.

Which holds more memory?

The DL360 Gen12 has 32 DIMM slots and a stated ceiling of 8.0 TB. The SR645 V3 has 24 and 6 TB.

Which takes more drives?

DL360 Gen12: 20 bays across 5 documented layouts. SR645 V3: 16 across 19. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

DL360 Gen12: up to 3 accelerators, 0 double-wide cards listed. SR645 V3: up to 5, 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. DL360 Gen12: HPE ProLiant Compute DL360 Gen12 QuickSpecs (Version 18 - 03-Aug-2026) (HPE document). SR645 V3: Lenovo ThinkSystem SR645 V3 Server Product Guide (publication date is not printed in the text export; guide contains 'New as of July 2026' notes) (Lenovo document). Each claim on this page is derived from those documents, checked page by page on the two data sheets, and carries no pricing.
