Dell R670 vs Lenovo SR630 V3
A specification-by-specification comparison of the Dell PowerEdge R670 and the Lenovo ThinkSystem SR630 V3, built from Dell’s and Lenovo’s own documents. 3 headline measures favour the R670 and none favour the SR630 V3, and they share no processors.
Bottom line. R670 leads on virtualisation, storage density, network throughput. Neither vendor publishes benchmarks for these machines, so every call here is made on what their documents state.
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 R670 if…
Cores, fully populated: 288 against 128 on the SR630 V3
Drive bays: 22 against 16 on the SR630 V3
Fastest network option: 400 GbE class against 200 GbE class on the SR630 V3
Up to 144 E-cores per socket — 288 cores in one rack unit — or 86 P-cores where per-core speed matters, all from one list of 23 processors.
Choose the SR630 V3 if…
Two sockets, 32 DDR5 slots and an 8 TB memory ceiling in 1U — the same ceiling Lenovo gives the 2U SR650 V3.

07 — Questions
R670 vs SR630 V3, answered
Is the R670 or the SR630 V3 the faster server?
Neither document publishes benchmark results, so this page compares what they do state. The R670 lists 23 processors up to 144 cores at 350 W; the SR630 V3 lists 84 up to 64 cores at 385 W. Fully populated that is 288 cores against 128.
Which holds more memory?
The R670 has 32 DIMM slots and a stated ceiling of 8 TB. The SR630 V3 has 32 and 8 TB.
Which takes more drives?
R670: 22 bays across 8 documented layouts. SR630 V3: 16 across 17. Counts include rear and mid-chassis positions where the vendor documents them.
Can either take GPUs?
R670: up to 3 accelerators, 0 double-wide cards listed. SR630 V3: up to 3, 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. R670: Dell PowerEdge R670 Technical Guide (May 2026, Rev. A07) (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.
