Inside Gen 13: how we built our most powerful server yet

Cloudflare’s Gen 13 server engineering post outlines the new 2U1N single-socket platform built around the AMD EPYC 9965 Turin 192-core processor with 768 GB DDR5-6400 (12x64GB), 3x E1.S PCIe 5.0 NVMe drives (24 TB), dual 100 GbE OCP 3.0 NICs, DC-SCM 2.0 management, PCIe encryption support, and a 1300W Titanium PSU. The write-up explains rationale for component choices driven by Cloudflare’s FL2 software (which scales with core count), targets for throughput, performance-per-watt, memory bandwidth and capacity (maintaining 4 GB/core), storage endurance and NVMe 2.0 features, thermal design, and operational/supply-chain considerations for deployment across its global fleet.
