Dell T160 vs Lenovo ST45 V3

A specification-by-specification comparison of the Dell PowerEdge T160 and the Lenovo ThinkSystem ST45 V3, built from Dell’s and Lenovo’s own documents. 2 headline measures favour the T160, 1 favours the ST45 V3, and they share no processors.

Bottom line. T160 leads on virtualisation, databases and in-memory work, storage density. 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 T160 if…

  • Memory ceiling: 0.125 TB against 0.0625 TB on the ST45 V3
  • Drive bays: 5 against 4 on the ST45 V3
  • Compact and quiet: 132.52 mm wide, 11.64 kg fully loaded, and measured at 28–29 dB at the bystander position in Dell’s idle and operating tests at 25 °C.

Choose the ST45 V3 if…

  • Cores, fully populated: 16 against 12 on the T160
  • Up to 16 cores in a desk-side box: the EPYC 4545P brings 16 cores and 32 threads, and every processor on the list, 4004 or 4005 series, is a 65 W part.

07 — Questions

T160 vs ST45 V3, answered

Is the T160 or the ST45 V3 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The T160 lists 19 processors up to 12 cores at 95 W; the ST45 V3 lists 8 up to 16 cores at 65 W. Fully populated that is 12 cores against 16.

Which holds more memory?

The T160 has 4 DIMM slots and a stated ceiling of 128 GB. The ST45 V3 has 2 and 64 GB.

Which takes more drives?

T160: 5 bays across 3 documented layouts. ST45 V3: 4 across 2. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

Neither vendor document lists an accelerator option for these models.

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. T160: Dell PowerEdge T160 Technical Guide (August 2026, Rev. A06) (Dell document). ST45 V3: Lenovo ThinkSystem ST45 V3 Server Product Guide (no revision date printed in text (related-publication timestamps run to 2026-07-14)) (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.
