Summary

In addition to the Surface Laptop Ultra , Microsoft has another device coming that's powered by NVIDIA's RTX Spark chip : the creatively named Surface RTX Spark Dev Box. Announced at Build today, it's basically a desktop version of the Laptop Ultimate built for sustained AI work like "long-running training jobs, agentic Al pipelines and local model fine-tuning," according to Microsoft. Naturally, the Dev Box can also handle more heat, thanks to its 100W thermal envelope (and low power Arm CPUs).
