Dell XE7740 vs Lenovo SR860 V3
A specification-by-specification comparison of the Dell PowerEdge XE7740 and the Lenovo ThinkSystem SR860 V3, built from Dell’s and Lenovo’s own documents. 3 headline measures favour the XE7740, 4 favour the SR860 V3, and they share no processors.
Bottom line. XE7740 leads on AI and acceleration, network throughput. SR860 V3 leads on virtualisation, databases and in-memory work, storage density. 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.
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 XE7740 if…
- Accelerators: Up to 16 against Up to 8 on the SR860 V3
- Largest power supply: 3,200 W against 2,700 W on the SR860 V3
- Fastest network option: 400 GbE class against 200 GbE class on the SR860 V3
- Eight double-wide slots at up to 600 W accept five different cards — NVIDIA H100 NVL, H200 NVL, L40S and RTX Pro 6000, or Intel Gaudi 3 — or sixteen single-width L4s.
Choose the SR860 V3 if…
- Processor sockets: 4 against 2 on the XE7740
- Cores, fully populated: 240 against 172 on the XE7740
- Memory ceiling: 16 TB against 4 TB on the XE7740
- Forty-eight front bays in one chassis: all SAS/SATA, or 24 SAS/SATA plus 24 AnyBay with each AnyBay bay on its own Gen5 x4 NVMe link.

XE7740 vs SR860 V3, answered
Is the XE7740 or the SR860 V3 the faster server?
Neither document publishes benchmark results, so this page compares what they do state. The XE7740 lists 3 processors up to 86 cores at 350 W; the SR860 V3 lists 10 up to 60 cores at 350 W. Fully populated that is 172 cores against 240.
Which holds more memory?
The XE7740 has 32 DIMM slots and a stated ceiling of 4 TB. The SR860 V3 has 64 and 16 TB.
Which takes more drives?
XE7740: 8 bays across 1 documented layouts. SR860 V3: 48 across 2. Counts include rear and mid-chassis positions where the vendor documents them.
Can either take GPUs?
XE7740: up to 16 accelerators, 5 double-wide cards listed. SR860 V3: up to 8, 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. XE7740: Dell PowerEdge XE7740 Technical Guide (Rev. A04, April 2026) (Dell document). SR860 V3: Lenovo ThinkSystem SR860 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.
