NVIDIA RTX Spark Brings 1 Petaflop AI Acceleration to Windows PCs

NVIDIA launched RTX Spark, a 1 petaflop AI superchip for Windows PCs, with Microsoft optimizing Windows for local AI agents. The Silicon Review reports on the fall 2026 rollout from major OEMs.

NVIDIA has officially launched RTX Spark, a new NVIDIA AI superchip designed to bring 1 petaflop of AI performance to Windows laptops and small-form-factor desktop PCs. Announced at GTC Taipei, the chip represents NVIDIA's entry into the Windows PC processor market, developed in collaboration with MediaTek and optimized with Microsoft.

The nvidia ai technology integrates a Blackwell RTX GPU with up to 6,144 CUDA cores and a 20-core Grace CPU built on Arm architecture, connected via NVLink-C2C with 600GB/s of bandwidth. The platform supports up to 128GB of unified LPDDR5X memory, enabling local execution of large language models with up to 120 billion parameters and 1 million tokens of context length.

Microsoft has optimized Windows for RTX Spark, introducing workload profile scheduling (WPS) and enabling the Microsoft Power and Thermal Framework (MPTF) to balance performance, battery life, and heat. The Prism emulator for x86 apps has been tuned for the RTX Spark microarchitecture.

The nvidia ai chip can render 90GB 3D scenes, edit 12K video, generate 4K AI video, and play AAA games at 1440p resolution exceeding 100 FPS with ray tracing and DLSS enabled . Adobe is rebuilding Photoshop and Premiere from the ground up for RTX Spark, promising up to 2x AI and graphics performance.

NVIDIA and Microsoft are also building a native Windows platform for local AI agents, with NVIDIA bringing OpenShell to Windows using new security and containment primitives. Hermes Agent and OpenClaw will integrate OpenShell into their Windows applications, enabling secure on-device agent execution.

First RTX Spark devices will arrive in fall 2026 from ASUS, Dell, HP, Lenovo, Microsoft Surface, and MSI. Acer and GIGABYTE will follow later. The Microsoft Surface Laptop Ultra was named as a launch device, alongside ASUS ProArt, Dell XPS 16 Creator Edition, HP OmniBook, Lenovo Yoga Pro 9n, and MSI Prestige N16 Flip AI+.
