HPE Compute XD690 vs Lenovo SR680a V3
A specification-by-specification comparison of the HPE Compute XD690 and the Lenovo ThinkSystem SR680a V3, built from HPE’s and Lenovo’s own documents. None of the headline measures favour the Compute XD690; 3 favour the SR680a V3, and they share no processors.
Bottom line. SR680a 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 Compute XD690 if…
- Eight NVIDIA Blackwell Ultra GPUs on an HGX B300 board in a chassis designed for air-cooled infrastructure, with ARCS or a rear door heat exchanger as options.
Choose the SR680a V3 if…
- Memory ceiling: 4 TB against 3 TB on the Compute XD690
- Drive bays: 16 against 8 on the Compute XD690
- Rack height: 8U Rack against 10U Rack on the Compute XD690
- 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.

Compute XD690 vs SR680a V3, answered
Is the Compute XD690 or the SR680a V3 the faster server?
Neither document publishes benchmark results, so this page compares what they do state. The Compute XD690 lists 2 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 Compute XD690 has 32 DIMM slots and a stated ceiling of 3 TB practical ceiling. The SR680a V3 has 32 and 4 TB.
Which takes more drives?
Compute XD690: 8 bays across 1 documented layouts. SR680a V3: 16 across 1. Counts include rear and mid-chassis positions where the vendor documents them.
Can either take GPUs?
Compute XD690: up to 8 accelerators, 0 double-wide cards listed. SR680a 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. Compute XD690: HPE Compute XD690 QuickSpecs (Version 6 - 06-July-2026) (HPE 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.
