Amazon announces new data center chip as Microsoft rivalry intensifies

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.
