Meta will begin deploying its third‑generation MTIA 450 AI chip in data centers in the first half of 2027, with the MTIA 500 slated for a broader rollout by the end of 2027.
Meta announced that its third‑generation custom AI processor, the MTIA 450, will start running in the company’s data centres in the first half of 2027, with the follow‑on MTIA 500 slated for a broad rollout by the end of the same year, Bloomberg reported. The chips belong to Meta’s Meta Training and Inference Accelerator (MTIA) family, which the company unveiled in March 2026 alongside the MTIA 300 and MTIA 400.
The move signals Meta’s push to replace Nvidia‑based GPUs for large‑scale inference workloads. According to the briefing, the MTIA 450 is tuned for generative‑AI inference, offering higher performance‑per‑watt and lower cost than comparable Nvidia systems. It also doubles the high‑bandwidth memory (HBM) bandwidth of the MTIA 400, a claim Meta says translates into “much higher” performance than existing commercial products. The later MTIA 500 is positioned as the next step in the roadmap, completing an 18‑month, four‑generation rollout that will see all four chips deployed by the close of 2027.
Why it matters is twofold. First, owning the silicon stack gives Meta tighter control over the energy efficiency and pricing of the massive inference workloads that power its feeds, recommendation engines and emerging generative‑AI services. Second, the strategy directly challenges Nvidia’s dominance in the data‑centre AI market, potentially reshaping supplier dynamics for the broader tech ecosystem.
What to watch next includes Meta’s first‑stage integration of the MTIA 450 and any early performance benchmarks that compare it with Nvidia’s latest GPUs. Observers will also be keen on the timing and scale of the MTIA 500 launch, as well as whether the company expands the chip family beyond 2027 or opens the silicon to external partners. The rollout will be a litmus test for Meta’s ambition to become a self‑sufficient AI hardware player.
