Nvidia Corp., whose chip technology dominates in data centers used to create artificial intelligence software, announced new products to help the personal computer industry lure consumers with “AI PCs.” Nvidia unveiled three new desktop graphics chips with extra components that will let gamers, designers and other computer users make better use of AI on their personal machines without having to rely on remote services accessed over the internet. The chips, updated versions of existing offerings, will be offered at a “great new price,” the company said Monday in a presentation at the CES trade show.
