The upcoming Microsoft Surface Laptop Ultra is poised to be one of the first devices utilizing Nvidia’s RTX Spark, an Arm-based chip tailored for Windows PCs. This high-performance laptop aims to cater to creators, developers, and AI builders, offering up to 128GB of unified memory. While Microsoft has announced that the Laptop Ultra will be available later this year, specific details regarding pricing and configuration options remain undisclosed.
Positioned above the existing Qualcomm Snapdragon-based Surface Laptops, the Laptop Ultra represents a shift in Microsoft’s design philosophy. Unlike previous high-end Surface devices, which featured convertible designs, the Laptop Ultra is designed to follow a more traditional laptop format, akin to the MacBook Pro. This model aims to deliver enhanced power without the complexities of a convertible mechanism.
Design and Connectivity
The Laptop Ultra will include a range of connectivity options, featuring USB-A, USB-C, and HDMI ports, along with an SD card slot and a headphone jack. Additionally, it will boast a haptic trackpad, described as the largest ever used in a Surface device. The display will be a 15-inch PixelSense screen capable of reaching up to 2,000 nits of peak brightness.
Internal Specifications
At the core of the Laptop Ultra is Nvidia’s RTX Spark, which features up to 20 Arm CPU cores—comprising 10 high-performance cores and 10 efficiency cores. The GPU component includes up to 6,144 Blackwell-based GPU cores, providing performance comparable to a desktop GeForce RTX 5070, albeit within a lower 80 W power envelope and utilizing LPDDR5x RAM instead of GDDR7.
A notable advantage of the RTX Spark is its unified memory architecture, allowing the GPU to access a significant portion of the system’s memory. This contrasts with traditional GPUs, which may have limited memory access. For instance, a laptop with 32GB of RAM could allocate more memory to the GPU than higher-end models like the GeForce RTX 4090 or 5090.
Gaming and Software Compatibility
While gaming performance on Arm-based Windows systems has historically been a challenge, both Nvidia and Microsoft are collaborating with developers to enhance compatibility with popular online games that utilize kernel-level anti-cheat software. The integration of Microsoft’s Prism x86-to-Arm code translation technology and an increasing number of Arm-native applications are making Arm-powered Windows PCs more viable for general use compared to earlier iterations.
Historically, Microsoft has utilized Nvidia’s chips in Surface devices, notably with the original Surface RT models, which ran a limited version of Windows 8. The lessons learned from that experience have informed the development of the current Arm-based Windows offerings.
