Introducing a powerful new chapter for Windows PCs, accelerated by NVIDIA RTX Spark
By
Pavan Davuluri, Executive Vice President, Windows + Devices
Today at NVIDIA GTC, Microsoft and NVIDIA announced the world’s most powerful and efficient thin-and-light Windows PCs ever. Accelerated by NVIDIA RTX Spark, these new PCs unlock incredible momentum for developers, creators and power users, and are purpose-built for the new wave of agents.
This marks a key milestone in the rich, multi‑year, full‑stack collaboration between Microsoft and NVIDIA spanning gaming, AI and cloud – from DirectX and RTX to NVIDIA‑accelerated AI workloads on Azure – driving end-to-end innovation for our shared customers. These next-generation Windows PCs represent the next step on that journey.
Builders and creators today are reimagining how things get done, and they need reimagined hardware, silicon and platform capabilities to support them. They need PCs capable of running graphically intensive tasks efficiently, highly capable AI models, and a platform that simply and securely runs agents locally. It’s the combination of Windows’ platform and ecosystem leadership, with NVIDIA’s silicon innovation and industry-leading graphics and AI leadership, that has resulted in a collection of powerhouse laptops that will redefine how developers and creators interact with their PCs.
“NVIDIA and Microsoft share a vision that agents are the future of personal computing,” said Jeff Fisher, senior vice president of personal computing at NVIDIA. “RTX Spark combines NVIDIA’s full technology stack with Microsoft Windows and is purpose-built for creators, gamers and AI developers in the personal AI era.”
Taking Windows to the next level on RTX Spark
RTX Spark delivers 1 petaflop of AI performance, industry-leading performance-per-watt, full stack NVIDIA AI and RTX graphics technology, with up to 6144 Blackwell RTX cores, up to 20 power-efficient cores built with the Arm architecture and up to 128GB of unified memory.
Paired with Windows, it unlocks the capabilities creators and developers need to run advanced workloads, build with the tools they depend on and even play their favorite games. Bringing Windows to RTX Spark enables you to do the work that matters on silicon that delivers the performance you demand.
Great silicon deserves deep platform work. We tuned Windows to bring out the full performance of RTX Spark.
Performance and power management
To get the most out of Windows on RTX Spark’s powerful, heterogeneous architecture, we implemented workload profile scheduling (WPS) and optimized it for RTX Spark, enabling the Windows scheduler to more efficiently scale workloads across all 20 cores. Whether you’re checking your email or running an agent locally to debug code, the Windows scheduler on RTX Spark will ensure you get the best performance and efficiency out of your CPU.
We also worked with NVIDIA to enable the Microsoft Power and Thermal Framework (MPTF) on RTX Spark, to maximize performance and power on the go. MPTF standardizes one of the most complex parts of a modern PC and will enable RTX Spark based PCs to deliver industry-leading power efficiency while staying cool under intense workloads.
Beyond its industry-leading performance per watt for creative, AI and gaming workloads, RTX Spark is positioned to take advantage of our advancements to DirectX 12, including support for neural rendering and optimized ray tracing performance, and has been tuned to maximize the performance of its Blackwell GPU, making it one of the best places to play on Windows. In addition, Microsoft and NVIDIA have worked to unlock the power of the GPU for local AI workloads through Windows ML, enabling AI developers to leverage TensorRT natively in Windows.
