Windows 10: Microsoft Announces Surface Laptop Ultra With NVIDIA Blackwell RTX GPU and 128GB Unified Memory

Microsoft has announced the Surface Laptop Ultra, calling it the most powerful Surface laptop to date. Developed in partnership with NVIDIA, it features an NVIDIA Blackwell RTX GPU along with up to 128GB of unified memory and full CUDA support. Microsoft is targeting creators, developers, and AI professionals running demanding local workloads.

The device is expected to be available later this year. This marks the first Surface laptop to combine an NVIDIA Blackwell RTX GPU with unified memory and CUDA, indicating an expanded hardware partnership between Microsoft and NVIDIA on the Windows platform.

Performance and Local AI Capabilities of Surface Laptop Ultra


The Surface Laptop Ultra's main feature is its local AI computing power. Microsoft says the device offers one petaflop of AI compute, based on NVIDIA's FP4 TOPS figure that uses the sparsity feature.

It can run models with up to 120 billion parameters locally. The device also has up to 128GB of unified memory that is dynamically shared between the CPU and GPU.

This unified memory setup allows the RAM to be allocated where it's most needed, supporting AI creation, 3D rendering, and workflows involving multiple models running at the same time. The device is optimized for RTX Spark and tuned for Windows.

Microsoft states the CPU architecture is designed to be power-efficient enough for all-day battery life, although the company notes that battery figures are based on internal testing of pre-release units and may vary depending on usage.

Display, Design, and Availability of Surface Laptop Ultra


The Surface Laptop Ultra has a 15-inch mini-LED PixelSense Ultra touchscreen that offers several notable features.

It can reach up to 2,000 nits of peak HDR brightness, making it the brightest display Microsoft has shipped. The screen has a pixel density of 262 pixels per inch and provides high-quality color accuracy. The device also includes the largest haptic touchpad seen on a Surface to date.

The Surface Laptop Ultra is part of a broader effort to introduce high-performance NVIDIA silicon into Windows laptops. It follows a series of teasers from NVIDIA, Microsoft, and Arm hinting at a "new era of PC" announcement at Computex 2026, where NVIDIA is expected to unveil its N1 consumer CPU.

The Surface Laptop Ultra reflects Microsoft's hardware contribution to this direction, with a focus on local AI workloads rather than relying on cloud-based processing.

The Surface Laptop Ultra is expected to launch later this year. Microsoft has not disclosed details about pricing, specific configurations, CPU specifications, or regional availability.

The company mentions that the device is a pre-release product, meaning features could change and depend on regulatory approval in different regions.

Windows 10 Nvidia Quadro M1000M GPU not working after installing external GPU NVidia GeForce RTX 3060

I have a Lenovo P50 laptop with an internal Quadro m1000m GPU. I installed recently an external NVidia GeForce RTX 3060 GPU (thunderbolt attached), and the internal Quadro m1000m GPU gets a Code 31 in device manager.

The NVidia GeForce RTX 3060 GPU driver does not list Quadro m1000m as supported.

Is it possible to have multiple GPUs with different NVidia drivers on Windows 10?
