HPE DL320 Gen11 vs Lenovo SR635 V3

A specification-by-specification comparison of the HPE ProLiant DL320 Gen11 and the Lenovo ThinkSystem SR635 V3, built from HPE’s and Lenovo’s own documents. 1 headline measure favours the DL320 Gen11, 5 favour the SR635 V3, and they share no processors.

Bottom line. SR635 V3 leads on virtualisation, databases and in-memory work, storage density, AI and acceleration, 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 DL320 Gen11 if…

  • Largest power supply: 2,200 W against 1,800 W on the SR635 V3
  • Four chassis on one platform — 4 LFF, 8+2 SFF, 12 LFF and GPU Dense — so the same model covers a branch file server, a 1U disk shelf or an accelerator node.

Choose the SR635 V3 if…

  • Cores, fully populated: 160 against 64 on the DL320 Gen11
  • Memory ceiling: 3 TB against 2.04 TB on the DL320 Gen11
  • Drive bays: 16 against 12 on the DL320 Gen11
  • All twelve DDR5 channels belong to the one processor, so a single socket still reaches 3 TB with 256 GB 3DS RDIMMs, and 5th Gen EPYC can clock that memory at up to 6400 MHz.

07 — Questions

DL320 Gen11 vs SR635 V3, answered

Is the DL320 Gen11 or the SR635 V3 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The DL320 Gen11 lists 46 processors up to 64 cores at 330 W; the SR635 V3 lists 45 up to 160 cores at 400 W. Fully populated that is 64 cores against 160.

Which holds more memory?

The DL320 Gen11 has 16 DIMM slots and a stated ceiling of 2.04 TB. The SR635 V3 has 12 and 3 TB.

Which takes more drives?

DL320 Gen11: 12 bays across 7 documented layouts. SR635 V3: 16 across 14. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

DL320 Gen11: up to 4 accelerators, 3 double-wide cards listed. SR635 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. DL320 Gen11: HPE ProLiant DL320 Gen11 QuickSpecs (Version 41 - 03-Aug-2026) (HPE document). SR635 V3: Lenovo ThinkSystem SR635 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.
