Microsoft, Nvidia, and MediaTek are working together on “RTX Spark,” a new chip for Windows PCs that’s all about AI, but if you look beyond that, it sounds like it might still be a good chip in general.
As per usual with any big tech launch in 2026, the messaging around the new RTX Spark chipset is all about AI, specifically about AI agents. Nvidia explains that Spark “powers the world’s first Windows PCs purpose-built for personal agents, featuring 1 petaflop of AI performance, industry-leading power efficiency, full-stack NVIDIA AI and graphics technology, and up to 128GB of unified memory” with Microsoft building “a native Windows experience for personal agents.”
Okay.
While the focus is very clearly on AI here, it sounds like RTX Spark is a powerhouse of a chip for Windows PCs in general, delivering massive performance and “all-day battery life” based on Arm architecture.
The RTX Spark, which Nvidia calls a “superchip,” includes an Nvidia RTX Blackwell RTX GPU and a 20-core Nvidia Grace CPU that was designed in collaboration with MediaTek. There are no specific benchmarks available, but Nvidia says that Spark “can render ultralarge 90GB 3D scenes with OptiX and DLSS, edit 12K 4:2:2 video with the NVIDIA Blackwell decoder, run 120-billion-parameter large language models with 1 million tokens context, and play AAA games at 1440p resolution and over 100 frames per second with ray tracing, DLSS and Reflex.” In other words, it sounds like an absolute powerhouse of a chip.
