Xiaomi's AI Cube runs 120B models locally at 1.22TB/s memory bandwidth
Xiaomi's AI Cube is a 150W mini-PC prototype that crams three of its own in-house chips (O3 mobile SoC, O100 AI accelerator, D100 automotive processor) into one desktop. The O100 alone hits 1.22TB/s of near-memory bandwidth, enough to run 120B-parameter models locally while switching between fast and slow systems. No price or release date yet.
