Two years ago, Cloudflare deployed our 12th Generation server fleet, based on AMD EPYC™ Genoa-X processors with their massive 3D V-Cache. That cache-heavy architecture was a perfect match for our request handling layer, FL1 at the time. But as we evaluated next-generation hardware, we faced a dilemma — the CPUs offering the biggest throughput gains came with a significant cache reduction. Our lega...
By upgrading to the Gen 13 servers, Cloudflare aims to improve its service performance and reduce environmental impact. However, the article reveals an interesting paradox: while the new servers offer twice the throughput, they maintain the same rack power budget, implying a potential trade-off between server density and energy efficiency at the edge of the network.
