Keynote: Building Data Center Scale SoC's using RISC-V at Meta

on YouTube ↗21m

" summary

Meta reports multiple deployed RISC‑V SoCs running production workloads and claims the video chip serves 100% of video uploads while replacing about 85% of CPU work. Measured gains include 9x throughput for H.264 and 50x for VP9 at ~9 W per chip (12 W per M.2). Designs use heavy core customization (custom instructions, registers, exceptions), an 8x8 PE array with two RISC‑V cores per PE, Zephyr for RTOS, and ask for matrix extensions, better LLVM support and standardized customization flows.
