AMD unveils AI chip to compete with Nvidia.

AMD has announced that it will start shipping its most advanced GPU for artificial intelligence, the MI300X, to some customers later this year. The move represents a challenge to Nvidia, which currently dominates the market for AI chips with over 80% market share. AMD's AI chips, which it calls "accelerators," could represent a big untapped market for the chipmaker, which is best known for its traditional computer processors. The MI300X can use up to 192GB of memory, which means it can fit even bigger AI models than other chips. AMD also said it would offer an Infinity Architecture that combines eight of its M1300X accelerators in one system.
