"The goal was to support workloads that now scale with parallelism rather than cache, enabling significantly higher request capacity and better performance-per-watt across Cloudflare's global edge infrastructure."
"Gen 13 is designed with a 192-core AMD EPYC Turin 9965 processor, 768 GB of DDR5-6400 memory, 24 TB of PCIe 5.0 NVMe storage, and a dual 100 GbE network interface card."
Cloudflare's Gen 13 servers utilize a 192-core AMD EPYC Turin 9965 processor and redesigned software to improve traffic handling. The new architecture allows for twice the traffic capacity of Gen 12 while maintaining response times. The changes result in 60% more capacity per rack without increased power consumption, enhancing memory, storage, and network bandwidth. The engineering choices focus on parallelism over cache, supporting higher request capacity and better performance-per-watt across Cloudflare's infrastructure.
