Head-to-head · every figure from the vendor documents
Dell R760xs vs Lenovo SR650 V3
A specification-by-specification comparison of the Dell PowerEdge R760xs and the Lenovo ThinkSystem SR650 V3, built from Dell’s and Lenovo’s own documents. None of the headline measures favour the R760xs; 6 favour the SR650 V3, and 21 processors appear in both lists.
Bottom line. SR650 V3 leads on virtualisation, databases and in-memory work, storage density, AI and acceleration, 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 R760xs if…
Storage breadth the 1U siblings cannot match: 24 front 2.5-inch bays (16 SAS/SATA plus 8 NVMe, up to 244.48 TB), or 8 or 12 × 3.5-inch bays up to 288 TB.
Choose the SR650 V3 if…
Cores, fully populated: 128 against 64 on the R760xs
Memory ceiling: 8 TB against 1.5 TB on the R760xs
Drive bays: 40 against 24 on the R760xs
Three drive zones — front, mid-chassis and rear — take the 2U chassis to 40 × 2.5-inch or 20 × 3.5-inch bays, and up to 36 NVMe drives can each run on a dedicated x4 link with no oversubscription.

07 — Questions
R760xs vs SR650 V3, answered
Is the R760xs or the SR650 V3 the faster server?
Neither document publishes benchmark results, so this page compares what they do state. The R760xs lists 21 processors up to 32 cores at 250 W; the SR650 V3 lists 84 up to 64 cores at 385 W. Fully populated that is 64 cores against 128.
Which holds more memory?
The R760xs has 16 DIMM slots and a stated ceiling of 1.5 TB. The SR650 V3 has 32 and 8 TB.
Which takes more drives?
R760xs: 24 bays across 7 documented layouts. SR650 V3: 40 across 20. Counts include rear and mid-chassis positions where the vendor documents them.
Can either take GPUs?
R760xs: up to 2 accelerators, 0 double-wide cards listed. SR650 V3: up to 8, 1 double-wide listed.
Do they share any processors?
Yes — 21 processors appear in both documents, including the Intel Xeon Gold 6448Y. That makes a like-for-like build possible on either server.
Where these figures come from. R760xs: Dell PowerEdge R760xs Technical Guide (June 2026, Rev. A04) (Dell document). SR650 V3: Lenovo ThinkSystem SR650 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.
