Dell R760xa vs Lenovo SR680a V3

A specification-by-specification comparison of the Dell PowerEdge R760xa and the Lenovo ThinkSystem SR680a V3, built from Dell’s and Lenovo’s own documents. 3 headline measures favour the R760xa, 2 favour the SR680a V3, and 2 processors appear in both lists.

Bottom line. R760xa leads on virtualisation, databases and in-memory work, storage density, AI and acceleration. SR680a V3 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 R760xa if…

  • Memory ceiling: 8 TB against 4 TB on the SR680a V3
  • Accelerators: Up to 12 against Up to 8 on the SR680a V3
  • Rack height: 2U Rack against 8U Rack on the SR680a V3
  • Twelve PCIe Gen5 slot positions in 2U: eight single-wide or four double-wide at the front, plus four full-height x16 slots at the rear for fabric or storage adapters.

Choose the SR680a V3 if…

  • Drive bays: 16 against 8 on the R760xa
  • Fastest network option: 400 GbE class against 100 GbE class on the R760xa
  • Eight B200 SXM6 GPUs on one HGX board; Lenovo’s GPU table gives each 180 GB of HBM3e at 8 TB/s, a 1000 W power rating and NVLink at 900 GB/s — 1,440 GB of GPU memory across the eight.

07 — Questions

R760xa vs SR680a V3, answered

Is the R760xa or the SR680a V3 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R760xa lists 30 processors up to 64 cores at 350 W; the SR680a V3 lists 6 up to 64 cores at 350 W. Fully populated that is 128 cores against 128.

Which holds more memory?

The R760xa has 32 DIMM slots and a stated ceiling of 8 TB. The SR680a V3 has 32 and 4 TB.

Which takes more drives?

R760xa: 8 bays across 5 documented layouts. SR680a V3: 16 across 1. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R760xa: up to 12 accelerators, 2 double-wide cards listed. SR680a V3: up to 8, 0 double-wide listed.

Do they share any processors?

Yes — 2 processors appear in both documents, including the Intel Xeon Platinum 8592+. That makes a like-for-like build possible on either server.

Where these figures come from. R760xa: Dell PowerEdge R760xa Technical Guide (June 2026, Rev. A06) (Dell document). SR680a V3: Lenovo ThinkSystem SR680a V3 with B200 Product Guide (July 15, 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.
