A heterogeneous solution of MediaTek CPU + Blackwell GPU—NVIDIA is about to break the moat of x86 laptops.

NVIDIA unveiled the RTX Spark SoC at GTC Taipei 2026. The SoC uses a 3nm dual-chiplet design: a MediaTek CPU (20-core ARM, including Cortex-X925 and Cortex-A725) and a Blackwell-architecture GPU, with 6144 CUDA cores, 1 PFLOP of AI computing power, and 128GB of unified memory shared across components. Its high-end performance targets the desktop RTX 5070. The system runs a traditional OS centered on large language models and supports autonomous agents. This fall release is developed in collaboration with partners including Dell, ASUS, Lenovo, and Microsoft.
