Global Context and Technological Gap

It's important to note that while HBM2 production represents a significant achievement for China's domestic industry, it still lags behind global industry leaders. Current cutting-edge memory technologies include HBM3E, with HBM4 on the horizon. For instance, NVIDIA's next-generation Rubin R100 AI GPU, expected to be unveiled at the GPU Technology Conference in March 2025, is anticipated to feature HBM4 memory 1
