<p>In this episode of This Week in NET, JQ Lau and Victor Hwang from our Network & Infrastructure Strategy team walk us through Cloudflare's 13th generation of servers — the machines that power a significant part of the internet across 330+ cities worldwide.</p><p><br></p><p>The Gen 13 program doubled compute density by jumping from 96 to 192 cores, but that came with an 83% drop in L3 cache. The team explains how a bold hardware bet, combined with Cloudflare's FL2 Rust-based software rewrite, turned that trade-off into a win across throughput, latency, and power efficiency.</p><p><br></p><p>From counterintuitive fan physics to credit card pen tests on chassis intrusion switches, this conversation covers the full stack: CPUs, memory, storage, networking, security, and what's next — including post-quantum readiness at the hardware layer.</p><p><br></p><p><strong>Mentioned blog posts:</strong></p><ul><li><a href="https://blog.cloudflare.com/gen13-launch/">Launching Cloudflare's Gen 13 servers: trading cache for cores for 2x edge compute performance </a></li><li><a href="https://blog.cloudflare.com/gen13-config/">Inside Gen 13: how we built our most powerful server yet</a></li></ul><p><br></p><p><strong>Timestamps</strong></p><p>00:53 — Blog recap: what Cloudflare announced (including agents can now actually create Cloudflare accounts, buy domains, and deploy)</p><p>03:52 — From Gen 11 to Gen 13: the evolution of Cloudflare's servers</p><p>05:04 — Doubling compute power while cutting cache by 83%</p><p>06:54 — The journey to choosing the right CPU</p><p>10:04 — Scratchpad vs bookshelf: cache and memory explained</p><p>12:08 — Why 192 cores won over 128 cores</p><p>15:35 — FL2: Cloudflare's Rust-based software rewrite</p><p>18:12 — Hardware and software co-design: why neither works alone</p><p>18:37 — Memory, storage, and networking upgrades</p><p>22:18 — Dual GPU support and future accelerators</p><p>23:25 — Inside the Gen 13 chassis: what changed visually</p><p>24:51 — Why adding a 5th fan saves power (counterintuitive physics)</p><p>25:59 — Server security: memory encryption, PCIe encryption, intrusion detection</p><p>30:12 — 50% better performance per watt and what that means at scale</p><p>33:54 — The Austin lab: where hardware gets tested before production</p><p>35:10 — How AI helped design Gen 13</p><p>37:13 — 500 terabits per second: Cloudflare's network milestone</p><p>38:30 — What's next: Gen 14, rack-scale design, and post-quantum hardware</p><p>41:16 — Supply chain planning: lessons from COVID and the AI buildout</p><p><br></p>
