What are Cloudflare Gen 13 servers?

AMD EPYC Turin-based fleet with up to 192 cores, running FL2 Rust stack for 2x edge compute over Gen 12, trading cache for throughput without latency hits.

Will Cloudflare Gen 13 improve my Workers performance?

Yes, scales with cores, perfect for dynamic compute like AI inference—expect lower latency, higher RPS if your code's not cache-bound.

How does AMD Turin compare to Genoa-X?

Double cores (192 vs 96), better IPC/efficiency, but 6x less L3 cache per core—wins big with optimized software like FL2.
