Just says after announcing the RTX Spark powered Surface Laptop Ultra coming later this year, Microsoft has today announced a second RTX Spark device under the Surface portfolio, this time aimed solely at developers looking for a mini PC that can run sustained AI workloads with a 100W thermal envelope.
Officially dubbed the Surface RTX Spark Dev Box, this Microsoft-made mini PC will be made available to purchase later this year, and features one petaflip of AI compute power and 128GB of unified memory, which is capable of running up to 120B parameter models locally without needing to reach out to the cloud.
It also features WSL2 with native GPU passthrough, full CUDA support, Visual Studio Code, GitHub Copilot, and many other Microsoft-made developer tools pre-installed.
No other details about the device have been revealed, and pricing is still a mystery. But given how we know that RTX Spark devices won't be cheap, expect this device to cost somewhere in the thousands when it ships later this year.

The Surface RTX Dev Box will be Microsoft's first Surface branded mini PC. This isn't the first dev box that the company has shipped however. In 2023, Microsoft shipped the Windows Developer Kit, powered by a Snapdragon 8cx Gen3 with 32GB RAM, aimed at developers looking to build Windows apps for Arm.
The Surface RTX Spark Dev Box is a much more polished product, with a much wider target audience. It's for developers, but not just developers who want to build for Windows on Arm. It's for all developers, looking to build software and AI experiences. The company wants Windows to be the platform for developers, not just Windows developers.
We'll have more to share about the Surface RTX Spark Dev Box as information becomes available. In the meantime, is this a product you might be interested in buying? Let us know in the comments.
