CES 2026: Nvidia’s Rubin and Alpamayo, AMD’s Ryzen AI and other AI debuts

CES 2026 is underway in Las Vegas, with the show floor open to the public after a packed couple of days of press conferences from companies including Nvidia, Sony and AMD and previews from Sunday’s Unveiled event. AI framed much of the messaging across those presentations, even as hardware upgrades and oddities continued to populate the show floor.

Nvidia CEO Jensen Huang delivered a lengthy presentation that showcased the Rubin computing architecture, which is set to begin replacing the Blackwell architecture in the second half of this year and includes speed and storage upgrades. Nvidia also unveiled the Alpamayo family of open source AI models and tools intended for use by autonomous vehicles this year; senior reporter Rebecca Bellan said that approach mirrors the company’s broader efforts to make its infrastructure the Android for generalist robots.

AMD chair and CEO Lisa Su gave a keynote featuring partners such as OpenAI president Greg Brockman, Fei-Fei Li and Luma AI CEO Amit Jain, and outlined AMD’s push to expand AI on personal computers with its Ryzen AI 400 Series processors, a shift detailed by senior reporter Rebecca Szkutak.
