Dell XE7740 vs HPE Compute XD690
A specification-by-specification comparison of the Dell PowerEdge XE7740 and the HPE Compute XD690, built from Dell’s and HPE’s own documents. 4 headline measures favour the XE7740 and none favour the Compute XD690, and 1 processors appear in both lists.
Bottom line. XE7740 leads on virtualisation, databases and in-memory work, storage density, AI and acceleration. 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…
- Cores, fully populated: 172 against 128 on the Compute XD690
- Memory ceiling: 4 TB against 3 TB on the Compute XD690
- Accelerators: Up to 16 against Up to 8 on the Compute XD690
- 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 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.

XE7740 vs Compute XD690, answered
Is the XE7740 or the Compute XD690 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 Compute XD690 lists 2 up to 64 cores at 350 W. Fully populated that is 172 cores against 128.
Which holds more memory?
The XE7740 has 32 DIMM slots and a stated ceiling of 4 TB. The Compute XD690 has 32 and 3 TB practical ceiling.
Which takes more drives?
XE7740: 8 bays across 1 documented layouts. Compute XD690: 8 across 1. 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. Compute XD690: up to 8, 0 double-wide listed.
Do they share any processors?
Yes — 1 processor appears in both documents, including the Intel Xeon 6 6767P. That makes a like-for-like build possible on either server.
Where these figures come from. XE7740: Dell PowerEdge XE7740 Technical Guide (Rev. A04, April 2026) (Dell document). Compute XD690: HPE Compute XD690 QuickSpecs (Version 6 - 06-July-2026) (HPE document). Each claim on this page is derived from those documents, checked page by page on the two data sheets, and carries no pricing.
