Meta Announces Four MTIA AI Chip Generations in Two Years: MTIA 300–500 Roadmap

Meta has detailed a rapid four-generation MTIA chip roadmap (300, 400, 450, 500) developed in partnership with Broadcom, spanning ranking/recommendation inference and training through general GenAI workloads. Key advances include a 4.5x HBM bandwidth increase and 25x compute FLOPS improvement from MTIA 300 to 500, with MTIA 450 and 500 targeting GenAI inference with doubled and further-increased HBM bandwidth versus leading commercial products. MTIA 300 is in production for R&R training, MTIA 400 is lab-tested and entering deployment, while MTIA 450 and 500 are scheduled for mass deployment in early 2027 and 2027 respectively. The strategy emphasizes modular chiplet design and short iteration cycles to keep hardware aligned with rapidly evolving AI model requirements.
