Analyst Ming‑Chi Kuo says his latest industry survey shows NVIDIA has restarted
the Rubin CPX prefill‑optimized inference GPU project after a major redesign.
Production is expected to begin in 2027 Q1. The revised Rubin CPX delivers
compute close to standard Rubin GPUs, further improves prefill performance, has
a peak single‑chip power draw of 2,300W and is specified with 168GB of HBM4
memory.
