Dell R660 vs Lenovo SR630 V3

A specification-by-specification comparison of the Dell PowerEdge R660 and the Lenovo ThinkSystem SR630 V3, built from Dell’s and Lenovo’s own documents. None of the headline measures favour the R660; 1 favour the SR630 V3, and 45 processors appear in both lists.

Bottom line. SR630 V3 leads on 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 R660 if…

  • The same 51 processors and 32 DDR5 slots as the 2U R760 in a 1U chassis, with up to 64 cores per socket and 8 TB of memory.

Choose the SR630 V3 if…

  • Fastest network option: 200 GbE class against 100 GbE class on the R660
  • Two sockets, 32 DDR5 slots and an 8 TB memory ceiling in 1U — the same ceiling Lenovo gives the 2U SR650 V3.

07 — Questions

R660 vs SR630 V3, answered

Is the R660 or the SR630 V3 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R660 lists 51 processors up to 64 cores at 350 W; the SR630 V3 lists 84 up to 64 cores at 385 W. Fully populated that is 128 cores against 128.

Which holds more memory?

The R660 has 32 DIMM slots and a stated ceiling of 8 TB. The SR630 V3 has 32 and 8 TB.

Which takes more drives?

R660: 16 bays across 13 documented layouts. SR630 V3: 16 across 17. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R660: up to 3 accelerators, 0 double-wide cards listed. SR630 V3: up to 3, 0 double-wide listed.

Do they share any processors?

Yes — 45 processors appear in both documents, including the Intel Xeon Platinum 8592+. That makes a like-for-like build possible on either server.

Where these figures come from. R660: Dell PowerEdge R660 Technical Guide (June 2026, Rev. A01) (Dell document). SR630 V3: Lenovo ThinkSystem SR630 V3 Server Product Guide (publication date is not printed in the text export) (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.
