The company also unveiled Trainium2, an updated version of a processor designed for artificial intelligence (AI) systems. It will begin powering new services starting next year, Amazon said. That chip provides an alternative to so-called AI accelerators sold by Nvidia — processors that have been vital to the build-out of artificial intelligence services.
Amazon.com Inc.’s cloud-computing unit announced updated versions of its in-house computer chips while also forging closer ties with Nvidia Corp — dual efforts designed to ensure it can get enough supplies of crucial data-centre processors.
New homegrown Graviton4 chips will have as much as 30% better performance than their predecessors, Amazon Web Services (AWS) said at its annual re:Invent conference in Las Vegas. Computers using the processors will start coming online in the coming months.
