Invidia's developers conference dubbed the Super Bowl of AI, rolled into its second day with a highly anticipated announcement.

Chief Executive Jensen Huang took the stage before an audience of 25,000 to unveil Rubin. It's NVIDIA's next-generation

artificial intelligence chip, named after the astronomer who discovered dark matter.

Ruben boasts three times the computing power of NVIDIA's own Blackwell Ultra Chip. In his

more than two-hour-long presentation, Wong said the world needs a hundred times more computing power for advanced AI that his company considered necessary even a year ago.

Well, from new chips to new partners, NVIDIA also announced today it's linking up with General Motors to provide underlying tech for its autonomous driving fleet and new networking equipment that will help bring down energy costs.

Meanwhile, YUM Brands, the parent company of KFC, Taco Bell, and Pizza Hut, also said it's partnering with NVIDIA to provide AI-powered voice ordering at the drive-thru and over the phone.

Yumb Brands ultimately hopes the technology will replace the need

for human order takers. NVIDIA's technology will also be used to help spot fumbled orders

and filter online commentary about YM's restaurant brands to provide feedback to managers.

NVIDIA shares were down more than 3% on today's session amid a broad sell-off in tech stocks.

The NASDAQ composite index lost 1.7%.

Electric vehicle makers were a focus for investors.

Tesla shares resumed their decline and are on track for a record nine-week losing streak.

Analysts worry the brand is becoming increasingly politicized because of CEO Elon Musk's role in the

Trump administration. Shares of rival Chinese EV maker, BYD, though, drove to a record high in Hong Kong.

That's after the company took the wraps off new charging technology that it says allows its

cars to drive about 250 miles on just five minutes of charge time.
