According to Bernstein Research  nearly 10 per cent of servers worldwide contain Arm processors, and 40 per cent are located in China. But that total is beaten by Amazon which has slightly above half of the Arm server CPUs in the world deployed in its Amazon Web Services (AWS) datacentres.

Amazon uses its Graviton family of chips, designed by the Annapurna Labs division of Amazon Web Services and introduced to the world in 2018. These are marked “for internal use only.” The latest is the Graviton3E for high-performance computing application was introduced towards the end of 2022.

According to Bernstein, because these chips were optimised for the specific needs of AWS, the company can fit in more cores per socket or per rack, and the chips consume less power, translating to lower spending on space and cooling.
