Meta builds a 1700W superchip
Meta is developing a 1700W inference superchip and custom MTIA silicon delivering ~30 petaFLOPS and up to 512GB HBM, signalling hyperscalers are doubling down on bespoke AI hardware rather than relying on Nvidia/AMD/Intel/ARM. That’s a reminder large players are willing to verticalize hardware to optimize GenAI workloads. (techradar.com)
Meta published a four‑generation MTIA roadmap naming MTIA 300, 400, 450 and 500 and said it will ship a new generation roughly every six months, with the 450 and 500 targeted for mass deployment in early 2027. (about.fb.com) The MTIA 500 uses a 2×2 chiplet layout that separates compute, network and SoC chiplets and is specified to deliver about 10 petaflops of FP8 compute with HBM bandwidth near 27.6 TB/s. (datacenterdynamics.com)(tomshardware.com) MTIA 300 is built from one compute chiplet plus two network chiplets and its compute chiplet contains processing elements with two RISC‑V cores and a dot‑product engine; Meta lists MTIA 300 at ~1.2 petaflops FP8 with ~6.1 TB/s HBM bandwidth and 216 GB HBM capacity. (datacenterdynamics.com) Meta says MTIA 400 steps up to roughly 6 petaflops FP8, increases HBM capacity to 288 GB and HBM bandwidth to about 9.2 TB/s while providing 1.2 Tb/s scale‑up networking and 100 Gb/s scale‑out links. (datacenterdynamics.com) A single rack validated by Meta uses 72 MTIA 400 devices on a switched backplane to form one scale‑up domain and supports both air‑assisted liquid cooling and full liquid cooling for data‑center deployment. (datacenterdynamics.com) Meta developed the MTIA line in partnership with Broadcom and said the chips will be manufactured by TSMC, with VP of Engineering Yee Jiun Song framing the program as a way to diversify silicon supply and insulate Meta from price volatility. (tomshardware.com)(cnbc.com) Meta’s materials state compute increases ~25× from MTIA 300 to MTIA 500 and HBM bandwidth rises about 4.5× across the lineup, and Meta describes MTIA 400 as “raw performance competitive with leading commercial products” without naming specific competitors.
