Nvidia announces new AI chip for personal computers

Nvidia has announced the RTX Spark chip for consumer PCs, marking its entry into the personal AI market with new Windows laptops from major manufacturers like Lenovo, HP, and Dell launching in autumn. The move represents a "paradigm shift" for Nvidia from component supplier to PC architecture owner, directly challenging Intel, AMD, and Qualcomm while partnering with Microsoft to create AI-powered personal agents. Separately, the US tightened export restrictions on Nvidia's advanced chips to Chinese firms, continuing efforts to limit Beijing's access to cutting-edge AI technology.
