Amazon.com on Tuesday introduced its newest data center chip for its cloud computing service as competition with Microsoft to dominate the market for artificial intelligence heats up.

At a conference in Las Vegas, Amazon Web Services Chief Executive Adam Selipsky announced Graviton4, the cloud firm's fourth custom central processor chip, which it said is 30% faster than its predecessor. The news comes weeks after Microsoft announced its own custom chip called Cobalt designed to compete with Amazon's Graviton series.
