NVIDIA unveils RTX Spark superchip for AI-powered laptops

NVIDIA announced its RTX Spark system‑on‑chip at the Computex expo in Taiwan. Developed with MediaTek and Microsoft, the chip integrates a 20‑core ARM CPU, a Blackwell GPU with 6,144 CUDA cores, and up to 128 GB of unified memory. It can deliver up to one petaflop of AI performance, allowing local execution of large language models without internet connectivity.

The company positioned RTX Spark as the foundation for upcoming devices such as Microsoft’s Surface Laptop Ultra and future models from Dell, HP, ASUS and Lenovo, promising up to 40 % lower power consumption than traditional Intel laptops while supporting advanced graphics features like ray tracing and DLSS.

Key benefits highlighted include offline AI processing for data privacy, elimination of cloud‑based subscription fees, and a new architecture that removes traditional inter‑component communication channels, potentially reshaping the laptop market.
