Designing Edge Servers with Arm CPUs to Deliver 57% More Performance Per Watt

Cloudflare has recently switched to using Arm server CPUs for its servers, resulting in a 57% increase in internet requests processed per watt compared to their previous AMD Rome CPUs. This change is part of the company's ongoing efforts to improve energy efficiency and reduce its carbon footprint. The new Arm-based processors, designed by Ampere, have shown significant improvements over x86 CPUs, which continue to dominate global data center energy consumption. Cloudflare hopes that this move will encourage other manufacturers to prioritize energy efficiency in their designs.
