Moving Markets: Nvidia announced a new generation of artificial intelligence chip and software on Monday during the company's developer's conference in San Jose, California, boosting optimism in the company as it continues to be one of the frontrunners in the emerging AI sector.

Named Blackwell, the new generation of AI graphics processors are not a chip but a platform, according to CEO Jensen Huang, highlighting how the company plans to become less of a semiconductor juggernaut and more of a platfrom provider for other companies to build software on, like Apple (APPL  ) or Microsoft (MSFT  ).

The Blackwell processors are the company's successor to Hopper, or its current generation H100 chips which debuted in 2022, and include what Nvidia calls a "transformer engine specifically built to run transformers-based AI," that power popular technologies like ChatGPT.
