Nvidia has officially introduced the Nvidia RTX Spark, a new superchip made for Windows PCs that can run local AI agents.
The chip was created together with Microsoft. The idea is to turn the PC from a tool that only reacts to clicks into a smarter helper that can work more actively for the user.
RTX Spark combines Nvidia’s latest technology. It includes a Blackwell GPU with 6,144 CUDA cores and fifth-generation Tensor cores with FP4 support. The GPU is connected through NVLink-C2C to a custom 20-core ARM CPU made together with MediaTek.
The chip can support up to 128 GB of unified memory and can reach 1 petaflop of AI performance. Nvidia says it is also efficient enough for thin laptops with all-day battery life.

The main goal of RTX Spark is to help solve privacy and security concerns around AI agents on personal computers. Microsoft and Nvidia have built a special Windows system that works with Nvidia OpenShell. This lets popular open-source agent tools, such as OpenClaw and Hermes Agent, run locally and privately.
Users can choose exactly which apps and local files these agents can check. Sensitive data can also be hidden when some requests need to be sent to cloud-based language models. This should give users stronger control over their private data.
RTX Spark is not only made for AI agents. It is also aimed at developers, content creators, and gamers. It brings together Nvidia features such as CUDA, Tensor, DLSS, Reflex, and G-SYNC.
The chip can run local language models with up to 120 billion parameters and context windows of up to one million tokens.
For design work, it can render complex 3D scenes larger than 90 GB, handle video workflows in tools like ComfyUI, and edit video up to 12K 4:2:2. Adobe is also redesigning apps like Photoshop and Premiere Pro to use RTX Spark’s unified memory. This could double the speed of AI-powered tools such as Generative Fill.
The chip will also support DLSS 4.5 with Ray Reconstruction and RTX Video with Frame Generation 4X.
The first thin laptops and compact PCs with RTX Spark are expected this fall. Brands such as ASUS, Dell, HP, Lenovo, Microsoft Surface, and MSI are expected to launch devices with the chip. Microsoft will show more of these new Windows AI agent features during Microsoft Build on June 2 and 3.
