Microsoft Surface Laptop Ultra 15" Laptop (EP2-56959) - NVIDIA RTX Spark N1X, 24GB RAM, 512GB SSD, Windows 11 Pro

The most powerful Surface Laptop ever built. Engineered with all-new NVIDIA RTX Spark™ from the silicon up, Surface Laptop Ultra for Business is purpose-built around a new chip that combines an ultra-efficient CPU with a powerful NVIDIA Blackwell RTX GPU to deliver up to one petaflop of AI compute, capable of running up to 120B parameter models locally. Up to 128 GB of unified memory allows the pool of RAM to be dynamically allocated wherever your workloads need it most across CPU and GPU - enabling the execution of larger local AI models and enhancing graphics performance.

Next-generation NVIDIA silicon
All-new NVIDIA RTX Spark™ superchip combines up to 20-core CPU, powerful RTX GPU, and NPU in one streamlined piece of silicon—delivering up to one petaflop of AI compute and optimizing on-device agentic AI performance.

Unified memory—faster, more efficient
Up to 128 GB of unified memory gives CPU and GPU access to a shared pool, freeing up Surface Laptop Ultra for Business to handle larger AI models, render complex scenes, and run demanding tasks faster and more efficiently.

Stay unplugged longer with up to 15 hours of battery
Surface Laptop Ultra for Business maintains performance even while running on battery power, so you can use demanding apps, prototype, and compile code on the go without worrying about the outlet.

Apps and files launch with blazing speed
Upgradable Gen-5 SSDs quickly handle large files and complex builds so you can work without breaking your momentum. The SSDs are easily accessible for repair or replacement.

Portable power with Surface 140W USB-C Power Adapter ​for Business
This 140W USB-C charger is tailored specifically for Surface Laptop Ultra for Business and small enough to slip in your pocket so you can stay charged wherever work takes you.

All-new thermal system for sustained high performance
With 2.5-times the thermal capacity for heat dissipation than Surface Laptop (8th Edition), Surface Laptop Ultra for Business stays cool, even when work heats up.

Built-in intelligence, designed to run AI right on your device
Run intensive AI directly on-device
Unified memory enables Surface Laptop Ultra for Business to handle larger models and datasets on-device, helping keep sensitive data private, latency low, and reducing the need to spend on tokens.
Compatible with the AI tools you already use
Get access to the NVIDIA CUDA™ ecosystem—one of the industry's most widely used platforms for accelerated computing—alongside the full Windows AI stack for demanding AI, scientific, and creative work.
Creative AI workflows on-device
Apps can take advantage of the powerful GPU to run AI-powered noise reduction, intelligent masking, video upscaling, and AI-assisted code completion directly on-device.

Deeper shadows, brighter highlights
The 15-inch Mini-LED PixelSense™ Ultra touchscreen enables precise local dimming for deep blacks and bright highlights, essential for HDR content and photographers, colorists, and designers doing color-critical work.
