Microsoft only just announced a[new Surface Laptop Ultra](https://www.theverge.com/tech/940584/microsoft-surface-laptop-ultra-nvidia-rtx-spark-pictures)at the weekend, and it’s now revealing a miniature Surface PC aimed at developers\. The new Surface RTX Spark Dev Box is powered by Nvidia’s new Arm\-based RTX Spark chips, just like the Surface Laptop Ultra, and is optimized for sustained workloads and local AI tasks\. The Surface RTX Spark Dev Box looks a little like the top of an Xbox Series X console, with an aluminum chassis that also doubles as a heatsink\. It has a 100\-watt thermal envelope, slightly more than the 45\-watt\-to\-80\-watt thermal envelopes for Nvidia’s RTX Spark laptops\. This miniature Surface PC also has 128GB of unified memory, making it capable of running up to 120 billion parameter models locally\.

Developer Mode is enabled\. PowerShell 7 is the default shell\.” The RTX Spark Dev Box joins similar options from other OEMs that are embracing Nvidia’s new RTX Spark chips for miniature PCs\. It’s also a direct replacement for[Qualcomm’s canceled Snapdragon Dev Kit](https://www.theverge.com/2024/10/18/24273366/qualcomm-cancels-snapdragon-dev-kit-mini-windows-on-arm-pc), the miniature Windows on Arm PC that was originally supposed to ship two years ago\. The Dev Kit was supposed to help developers port their apps to Windows on Arm, but Qualcomm faced some complications with hardware quality\. While we don’t have full specifications or pricing, the RTX Spark Dev Box will be available later this year in the US from Microsoft’s online store\. **Follow topics and authors**from this story to see more like this in your personalized homepage feed and to receive email updates\. - Tom Warren
