China is stepping up its chip self-sufficiency push by combining relatively mature chips with new computing architectures in an effort to approach Nvidia’s performance levels, according to a top industry expert. Logic chips made with a 14-nanometre process, which are generally seen as trailing cutting-edge AI processors, could reach a performance comparable with Nvidia’s 4nm products if they were integrated with high-performance memory and an innovative computing architecture, said Wei Shaojun,...
