Google Cloud rolls out self-designed Arm chips in its data centers

Google is joining the custom Arm data center chip trend. Google Cloud, the cloud platform division that competes with AWS and Microsoft Azure, is following in the footsteps of those companies and rolling out its own Arm-based chip designs. Google says its new “Google Axion Processors” are “custom Arm-based CPUs designed for the data center” and offer “industry-leading performance and energy efficiency.”

Google has been doing custom data center accelerators for things like AI and video transcoding, but this is the first time the company is doing a CPU. Google says it’s seeing “50% better performance and up to 60% better energy-efficiency than comparable current-generation x86-based instances.“

Google’s “Axion” chip is based on the Arm Neoverse V2 CPU, so just like the ARM chips we see on mobile devices, by making “custom” chips, these companies are closely following a lot of blueprints that Arm makes available. Google says it did include a custom microcontroller called “Titanium,” which it says handles networking, security, and storage I/O.
