The AI chip market is experiencing a surge in interest for 3D stacking technologies, driven by the increasing demands of AI agents for greater memory capacity, bandwidth, and data efficiency. While companies are adopting various "3D stacking" approaches, these solutions address distinct problems and face different validation standards. Some focus on re-aggregating logic chiplets and expanding memory, similar to overseas approaches, while others, particularly domestic Chinese companies, are concentrating on vertically integrating logic and memory units. This strategic divergence is partly due to manufacturing constraints and the desire to innovate at the architecture and packaging level to compensate for limitations in advanced process nodes and high-bandwidth memory. Ultimately, the success of these 3D chips will depend on their ability to translate theoretical advantages into tangible performance gains, cost efficiencies, and real-world customer orders, especially in improving token throughput.
