Microsoft has unveiled its first custom silicon, launching two chips, the Maia 100 (M100) AI accelerator and the Cobolt 100 CPU, designed to handle artificial intelligence and general purpose workloads on its Azure cloud platform.

The two chips represent a first foray into semiconductors for Microsoft, and see the company follow in the footsteps of its public cloud rivals, Amazon's AWS and Google Cloud, which run their own chips in their datacentres alongside those provided by vendors such as Nvidia.
