Cambricon MLU370-X8
Overview
The Cambricon (寒武纪) MLU370-X8 is a dual-chip Siyuan 370 (思元370) training/inference accelerator built on TSMC 7nm (MLUarch03), launched March 2022. It is a full-height full-length dual-slot PCIe Gen4 card pairing two Siyuan 370 chips via an MLU-Link bridge (200 GB/s aggregate). Cambricon's official spec table lists 48 GB of LPDDR5 (not HBM) at 614.4 GB/s, a 250W board, and dense peaks of 24 TFLOPS FP32, 96 TFLOPS FP16/BF16, and 256 TOPS INT8. INT16 (128 TOPS) is published but has no matching precision column in this database and is omitted; the card has no FP8 or TF32 datapath.
