Dell R6625 vs HPE XD230
A specification-by-specification comparison of the Dell PowerEdge R6625 and the HPE ProLiant Compute XD230, built from Dell’s and HPE’s own documents. 2 headline measures favour the R6625, 3 favour the XD230, and they share no processors.
Bottom line. R6625 leads on virtualisation, databases and in-memory work, AI and acceleration. XD230 leads on storage density, 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.
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 R6625 if…
- Memory ceiling: 6 TB against 3 TB on the XD230
- Accelerators: Up to 2 against None listed on the XD230
- Two sockets in one rack unit: a pair of 128-core 9754s gives 256 cores, and Dell rates them for air at 30°C with the 8 × 2.5-inch NVMe front or no backplane.
Choose the XD230 if…
- Drive bays: 20 against 16 on the R6625
- Largest power supply: 3,200 W against 1,800 W on the R6625
- Fastest network option: 400 GbE class against 100 GbE class on the R6625
- Up to 128 cores per socket from five Xeon 6900P models (72 to 128 cores, 400 W or 500 W), each rated for DDR5-6400 and for 8800 MT/s multiplexed-rank memory.

R6625 vs XD230, answered
Is the R6625 or the XD230 the faster server?
Neither document publishes benchmark results, so this page compares what they do state. The R6625 lists 19 processors up to 128 cores at 360 W; the XD230 lists 5 up to 128 cores at 500 W. Fully populated that is 256 cores against 256.
Which holds more memory?
The R6625 has 24 DIMM slots and a stated ceiling of 6 TB. The XD230 has 24 and 3 TB.
Which takes more drives?
R6625: 16 bays across 14 documented layouts. XD230: 20 across 2. Counts include rear and mid-chassis positions where the vendor documents them.
Can either take GPUs?
R6625: up to 2 accelerators, 0 double-wide cards listed. XD230: no accelerator option in its document.
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. R6625: Dell PowerEdge R6625 Technical Guide (July 2026, Rev. A07) (Dell document). XD230: HPE ProLiant Compute XD230 QuickSpecs (Version 18 - 03-Aug-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.
