Launching Cloudflare’s Gen 13 servers: trading cache for cores for 2x edge compute performance

Cloudflare has announced Gen 13 servers, based on AMD EPYC Turin processors and shipping with the FL2 rewrite of its request handling layer, designed to unlock edge performance while meeting latency SLAs. The new generation doubles core count to up to 192 cores (384 threads) compared with Gen 12’s 96 cores, but trades larger per-core cache for higher throughput across more cores.

In initial testing, FL2 on Gen 13 delivers a 70% reduction in latency versus Gen 12 and enables throughput to scale with core count, with up to 2x the throughput reported for the high-density 9965 variant. Power efficiency also improves, with performance per watt up to 50% higher than Gen 12, supporting sustainable scaling.

Cloudflare notes Gen 13 is selected for deployment and is shipping at scale to support its global edge network, with a 60% higher rack throughput and a continued focus on maintaining strict latency SLAs as traffic spikes grow. 23 March 2026.
