Dell XR5610 vs Lenovo SE455 V3
A specification-by-specification comparison of the Dell PowerEdge XR5610 and the Lenovo ThinkEdge SE455 V3, built from Dell’s and Lenovo’s own documents. 1 headline measure favours the XR5610, 3 favour the SE455 V3, and they share no processors.
Bottom line. XR5610 leads on databases and in-memory work. SE455 V3 leads on virtualisation, 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 XR5610 if…
- Memory ceiling: 1 TB against 0.75 TB on the SE455 V3
- Two chassis orientations: Rear Accessed, or Front Accessed with power, network ports and PCIe slots all on the front face — useful in cabinets you can only reach from one side.
Choose the SE455 V3 if…
- Cores, fully populated: 64 against 32 on the XR5610
- Drive bays: 8 against 4 on the XR5610
- Accelerators: Up to 6 against Up to 2 on the XR5610
- At 440 mm deep, with rail kits for two-post, 600 mm and 1000 mm racks, it is shorter than a conventional rack server and built for tight spaces.

XR5610 vs SE455 V3, answered
Is the XR5610 or the SE455 V3 the faster server?
Neither document publishes benchmark results, so this page compares what they do state. The XR5610 lists 13 processors up to 32 cores at 205 W; the SE455 V3 lists 12 up to 64 cores at 200 W. Fully populated that is 32 cores against 64.
Which holds more memory?
The XR5610 has 8 DIMM slots and a stated ceiling of 1 TB. The SE455 V3 has 6 and 768 GB.
Which takes more drives?
XR5610: 4 bays across 3 documented layouts. SE455 V3: 8 across 4. Counts include rear and mid-chassis positions where the vendor documents them.
Can either take GPUs?
XR5610: up to 2 accelerators, 0 double-wide cards listed. SE455 V3: up to 6, 1 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. XR5610: Dell PowerEdge XR5610 Technical Guide (Rev. A02, December 2024) (Dell document). SE455 V3: Lenovo ThinkEdge SE455 V3 and SE455i V3 Servers Product Guide (no revision date printed in text (related-publication timestamps run to 2026-07-14)) (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.
