Dell R760 vs Lenovo SR650a V4

A specification-by-specification comparison of the Dell PowerEdge R760 and the Lenovo ThinkSystem SR650a V4, built from Dell’s and Lenovo’s own documents. 1 headline measure favours the R760, 3 favour the SR650a V4, and they share no processors.

Bottom line. R760 leads on storage density. SR650a V4 leads on virtualisation, 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 R760 if…

  • Drive bays: 28 against 8 on the SR650a V4
  • Dell documents 51 processor SKUs, 31 drive-bay layouts and 10 power supplies for this one chassis — far more choice than the R760xs, R760xd2 or R760xa siblings.

Choose the SR650a V4 if…

  • Cores, fully populated: 172 against 128 on the R760
  • Accelerators: Up to 8 against Up to 6 on the R760
  • Fastest network option: 800 GbE class against 200 GbE class on the R760
  • One 2U chassis spans eight low-profile L4 cards, four double-wide cards of up to 450 W, or a pair of 600 W H200 NVL or RTX PRO 6000 Blackwell GPUs, all in PCIe 5.0 front slots.

07 — Questions

R760 vs SR650a V4, answered

Is the R760 or the SR650a V4 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R760 lists 51 processors up to 64 cores at 350 W; the SR650a V4 lists 27 up to 86 cores at 350 W. Fully populated that is 128 cores against 172.

Which holds more memory?

The R760 has 32 DIMM slots and a stated ceiling of 8 TB. The SR650a V4 has 32 and 8 TB.

Which takes more drives?

R760: 28 bays across 30 documented layouts. SR650a V4: 8 across 4. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R760: up to 6 accelerators, 9 double-wide cards listed. SR650a V4: up to 8, 4 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. R760: Dell PowerEdge R760 Technical Guide (Rev. A06, June 2026) (Dell document). SR650a V4: Lenovo ThinkSystem SR650a V4 and SR650i V4 Servers (August 27, 2026) (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.
