HPE DL380a Gen12 vs Lenovo SR675 V3

A specification-by-specification comparison of the HPE ProLiant Compute DL380a Gen12 and the Lenovo ThinkSystem SR675 V3, built from HPE’s and Lenovo’s own documents. 4 headline measures favour the DL380a Gen12, 2 favour the SR675 V3, and they share no processors.

Bottom line. DL380a Gen12 leads on virtualisation, databases and in-memory work, storage density, 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 DL380a Gen12 if…

  • Memory ceiling: 8 TB against 6 TB on the SR675 V3
  • Drive bays: 16 against 8 on the SR675 V3
  • Accelerators: Up to 10 against Up to 8 on the SR675 V3
  • Ten double-wide GPU positions in 4U, with the H200 NVL, RTX PRO 6000 Blackwell, RTX PRO 6000D, L40S, L20 and L4 in HPE’s accelerator list.

Choose the SR675 V3 if…

  • Cores, fully populated: 320 against 288 on the DL380a Gen12
  • Rack height: 3U Rack against 4U Rack on the DL380a Gen12
  • Eight double-wide or single-wide PCIe GPUs fit in 3U on the 8-DW base, fed either by two direct x8 risers at 1:1 or by two switched x16 risers that share each host link between two cards.

07 — Questions

DL380a Gen12 vs SR675 V3, answered

Is the DL380a Gen12 or the SR675 V3 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The DL380a Gen12 lists 32 processors up to 144 cores at 350 W; the SR675 V3 lists 40 up to 160 cores at 400 W. Fully populated that is 288 cores against 320.

Which holds more memory?

The DL380a Gen12 has 32 DIMM slots and a stated ceiling of 8.0 TB. The SR675 V3 has 24 and 6 TB.

Which takes more drives?

DL380a Gen12: 16 bays across 2 documented layouts. SR675 V3: 8 across 3. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

DL380a Gen12: up to 10 accelerators, 0 double-wide cards listed. SR675 V3: up to 8, 5 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. DL380a Gen12: HPE ProLiant Compute DL380a Gen12 QuickSpecs (Version 20 - 08-Sep-2026) (HPE document). SR675 V3: Lenovo ThinkSystem SR675 V3 and SR675i V3 Servers Product Guide (August 25, 2026) (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.
