Cloudflare is quitting Intel: instead of sticking with x86 processors, the company is transitioning to ARM servers for its future data centers. CEO Matthew Prince stated that he would choose ARM even if Intel’s hardware was free, as the former delivers far better power efficiency.



The Cloudflare team (which includes former Intel engineers) didn’t initially expect ARM processors to perform so well for its needs, especially with the open source software the service is built on. “They started testing the workloads, and they were just blown away. It was so much easier than we thought it would be. Performance is already better, and the power performance is just incredible.”
