NVIDIA and Microsoft launch RTX Spark, an AI-focused 20-core "superchip" for Windows PC

NVIDIA, together with partner Microsoft, launched the RTX Spark.

NVIDIA RTX Spark is now official

Next-gen AI chip for Windows PCs

In summary, the NVIDIA RTX Spark is a new AI-focused superchip for Microsoft Windows PCs.

It is capable of delivering up to 1 petaflop of AI compute, comes with 128GB unified memory, and seamless integration with Microsoft’s Windows agent ecosystem.

The RTX Spark uses a 20-core NVIDIA Grace CPU, co-designed with MediaTek for efficiency and connectivity. It is paired with an NVIDIA Blackwell RTX GPU with 6,144 CUDA cores and 5th-gen Tensor Cores (FP4 precision). It also has an NVLink-C2C interconnect for ultra-fast CPU-GPU communication.

RTX Spark can run massive language models with up to 120 billion parameters and 1 million token contexts locally, removing reliance on the cloud.

It also supports Windows-native agents through Microsoft's new security primitives, ensuring safe integration.

Users will also gain secure and trustworthy agent execution with the NVIDIA OpenShell runtime, providing privacy, containment, and policy controls.

This enables advanced AI agents like Hermes Agent and OpenClaw to operate privately and effectively on Windows PCs.

For gaming, NVIDIA claims that it can run AA games at 1440p at 100+ FPS with ray tracing, DLSS, and Reflex. It also supports DLSS 4.5 Ray Reconstruction and RTX Video with 4x Frame Generation and integration with the XBOX PC gaming ecosystem and titles from NetEase, Remedy, Riot Games, and more.

The chip is also said to be optimized for creativity and productivity with up to 2x faster AI and graphics performance for Adobe Photoshop and Premiere. It can also handle 12K 4:2:2 video editing, 90GB+ 3D scene rendering, and 4K AI video generation. It is also said to be optimized for Substance 3D Painter, Stager, and GPU-accelerated compositing workflows.

NVIDIA and Microsoft aim to use this on slim laptops as thin as 14mm, weighing less than 3 pounds, and OLED G-SYNC displays, as well as compact desktops and premium builds from brands.

The chip will launch in fall 2026, with laptops and desktops from ASUS, Dell, HP, Lenovo, Microsoft Surface, MSI, and later Acer and GIGABYTE.
