Nvidia has wrapped its GTC keynote, but investors didn't seem too impressed, with shares ending the day down 3.4%.

Nvidia founder Jensen Huang kicked off the company’s artificial intelligence developer conference, on Tuesday by telling a crowd of thousands that AI is going through “an inflection point.”

Currently in production, Nvidia’s Blackwell Ultra series is an advanced iteration of the Blackwell chips unveiled at last year’s GTC, which are 40 times more powerful than the previous-generation Hopper chips, Huang said.
