Nvidia has unveiled its latest artificial intelligence (AI) chip which it says can do some tasks 30 times faster than its predecessor.Nvidia Chief Executive Jensen Huang on Monday kicked off his company's annual developer conference with a slew of announcements designed to keep the chip maker in a dominant position in the artificial-intelligence industry.He detailed a new set of software tools to help developers sell AI models more easily to companies that use technology from Nvidia, whose customers include most of the world's biggest technology firms.Nvidia's chip and software announcements at GTC 2024 will help determine whether the company can maintain its 80% share of the market for AI chips.Nvidia's new flagship chip, called the B200, takes two squares of silicon the size of the company's previous offering and binds them together into a single component.
