Microsoft Surface Laptop Ultra debuts with Nvidia RTX Spark and 128GB unified memory

At Computex 2026, Microsoft introduced the Surface Laptop Ultra as the flagship device for Nvidia’s new RTX Spark processor. This ARM-based system-on-chip packs a 20-core CPU, graphics on par with a GeForce RTX 5070, and up to 128GB of unified memory, delivering 1 petaflop of AI performance. The laptop is designed for AI power users and creators, enabling local execution of large language models and demanding creative tasks like video upscaling and intelligent masking. During a live demo, the Surface Ultra powered graphically intense games such as *Pragmata* and *Indiana Jones and the Great Circle* for several hours, remaining warm but quiet thanks to a redesigned dual-fan, dual-heat-pipe cooling system. The chassis is slightly raised for airflow, and a smoke machine demo was planned but malfunctioned.

The physical build is premium: a solid aluminum body with an edge-to-edge glass panel and a recessed chiclet keyboard. The 15-inch mini-LED PixelSense Ultra touchscreen offers a 3:2 aspect ratio, 262 ppi, and a peak brightness of 2,000 nits for exceptional HDR visuals. Ports include two USB-C, USB-A, HDMI, an SD card reader, and a headphone jack. Notably, Microsoft prioritized repairability with a removable backplate for easy access to the SSD and battery. The Surface Ultra was the only RTX Spark laptop powered on at Computex, underscoring Microsoft’s confidence. Hands-on impressions confirm smooth gaming and video editing performance, though real-world benchmarks are pending.
