Meta reveals four custom AI chips, claims they outperform commercial silicon

Social networking giant Meta has revealed details of four previously unknown custom chips powering its AI services.

The company signalled its intention to roll out more custom inferencing chips in 2024, and in a post about its custom silicon, reveals it built its latest chips “in close partnership with Broadcom.”

The post names the four previously unknown chips as models 300, 400, 450, and 500 in the Meta Training Inference Accelerator (MTIA) series, and says some are already running in production and others will appear this year or next. Broadcom has said Meta will install “multiple gigawatts” of its chips in 2027 and beyond.

Meta described the four chips as follows:

• MTIA 300: A communications chip optimized for ranking and recommendation (R&R) workloads, comprised of one compute chiplet, two network chiplets, and several HBM stacks. Each compute chiplet is composed of a grid of processing elements (PEs), with some redundant ...
