RTX Spark laptops are on sale: $2,599 to start, $5,899 for 128GB
Microsoft opened orders on Wednesday and five other makers follow on 16 October. The 128GB version is the one that runs the big models, and I would wait for independent tests before buying one.

The chip from NVIDIA's DGX Spark can now be ordered in a Windows laptop. Microsoft opened orders for its Surface Laptop Ultra on Wednesday 7 October. It goes on sale on Friday 16 October, along with RTX Spark laptops from ASUS, Dell, HP, Lenovo and MSI.
When I covered these laptops in September there were no prices. Now we have them for all three memory sizes.
The prices
| Memory | Storage | US | UK |
|---|---|---|---|
| 24GB | 512GB | $2,599.99 | £2,599 |
| 64GB | 1TB | $4,299.99 | £4,299 |
| 128GB | 1TB | $5,899.99 | £5,899 out of stock on 9 October |
Microsoft's US and UK stores on 9 October 2026. UK prices include VAT.
Microsoft is also selling a small desktop box with the same chip, the Surface RTX Spark Dev Box. It has 128GB and 2TB for $5,999.99 and will ship in November. So far I can only find it on the US store.
For comparison, NVIDIA's own 128GB DGX Spark was reported at $6,950 on 2 October and the new 64GB DGX Spark will be $4,999 from 23 October. So Microsoft's desktop box is $1,000.99 more than the 64GB Spark for twice the memory ($5,999.99 minus $4,999).
What will 128GB run?
NVIDIA's own example for these machines is Qwen 3.8 Flash Next. Artificial Analysis scored it at 40 points on 9 October. The GLM 5.3 Flash model that I run across four DGX Sparks scored 42.
Owners already run Flash Next on a single DGX Spark. One of them posted 71 to 72 tokens a second on NVIDIA's developer forum on 7 October, and another count in the same thread put it in the low 50s.
Microsoft's own chart for its laptop shows about 63 tokens a second, falling on a very long prompt. That is with a different model (MAI Code 1.1 Flash) and I read the figures off the chart myself.
A few caveats
- Those models all need the 128GB version.
- Even then, Microsoft's own screenshot shows Windows giving the graphics side 110 of the 128GB.
- NVIDIA lists the laptop chip at 45 to 80 watts and the desktop one at 140. I would not expect a laptop to keep up with a desktop box for long.
- I cannot find any independent test of the RTX Spark's AI speed yet.
What I would do
I would wait for the first independent tests, and I would only look at the 128GB version.
