GitHub Actions now offers Arm-hosted runners with images built by Arm for developers to build on the latest processors. These new Arm-based Linux and Windows runners provide power, performance, and sustainability improvements for GitHub Actions jobs at a 37% lower price than x64 runners. Users can take advantage of Arm architecture for increased performance and efficiency while reducing their carbon footprint. Partnerships with Arm and NVIDIA ensure a wide range of image options for developers. Arm-hosted runners are available to GitHub Team and Enterprise Cloud plan customers, with open-source availability expected soon. Customers can reduce energy consumption and heat generation using these new runners while improving sustainability.
