Dell R670 vs Lenovo SR630 V4

A specification-by-specification comparison of the Dell PowerEdge R670 and the Lenovo ThinkSystem SR630 V4, built from Dell’s and Lenovo’s own documents. 1 headline measure favours the R670, 2 favour the SR630 V4, and 23 processors appear in both lists.

Bottom line. R670 leads on storage density. SR630 V4 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 R670 if…

  • Drive bays: 22 against 16 on the SR630 V4
  • 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 V4 if…

  • Largest power supply: 2,000 W against 1,800 W on the R670
  • Fastest network option: 800 GbE class against 400 GbE class on the R670
  • Two processor families in one 1U chassis: 27 Xeon 6 P-core SKUs of up to 86 cores, and seven 6700E E-core SKUs of up to 144 cores for thread-dense scale-out work.

07 — Questions

R670 vs SR630 V4, answered

Is the R670 or the SR630 V4 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 V4 lists 34 up to 144 cores at 350 W. Fully populated that is 288 cores against 288.

Which holds more memory?

The R670 has 32 DIMM slots and a stated ceiling of 8 TB. The SR630 V4 has 32 and 8 TB.

Which takes more drives?

R670: 22 bays across 8 documented layouts. SR630 V4: 16 across 14. 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 V4: up to 3, 0 double-wide listed.

Do they share any processors?

Yes — 23 processors appear in both documents, including the Intel Xeon 6 6780E. That makes a like-for-like build possible on either server.

Where these figures come from. R670: Dell PowerEdge R670 Technical Guide (May 2026, Rev. A07) (Dell document). SR630 V4: Lenovo ThinkSystem SR630 V4 Server Product Guide (September 8, 2026 (created or updated)) (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.
