Nvidia’s RTX Spark PCs arrive this month, and Microsoft’s October 7 event will put local AI front and centre. Here is what the shift means for buyers.

Local AI means the computer runs AI models on the device itself instead of sending every request to cloud servers. That can reduce delay, improve privacy, let some features work offline and cut recurring cloud costs.

The RTX Spark platform packs a 20-core Grace CPU and a Blackwell GPU with up to 1 petaflop of AI compute and up to 128GB of unified memory. Nvidia says such PCs can run models with up to 120 billion parameters entirely on-device.

Six notebook families are confirmed, including models from ASUS, Dell, HP, Lenovo, Microsoft and MSI. Google’s new Googlebook laptops, built around Gemini, go on sale in the US on October 4, adding competition.

What to expect: premium notebooks first, around 14mm thick and three pounds, aimed at creators and professionals. Prices and battery life are still unannounced, and independent testing will be needed to verify the AI claims.

For most buyers, the practical question is simple: how much faster and more private will everyday AI tasks feel? October’s launches should start answering that.
