Huawei is preparing to unveil what it calls a major breakthrough in AI inference at the 2025 Financial AI Inference Application Implementation and Development Forum on August 12.
Early reports from China suggest the technology could reduce China’s reliance on High Bandwidth Memory (HBM), a crucial component in AI systems, while improving the performance of domestic large-model inference. The move could have implications not only for China’s AI ecosystem but also for the broader global tech landscape.
What Makes HBM Important
HBM, or High Bandwidth Memory, is a type of DRAM built using 3D stacking, where multiple DRAM chips are vertically integrated to deliver far greater data transfer speeds than conventional memory. Known for its ultra-high bandwidth, low latency, and energy efficiency, HBM is essential for demanding AI workloads.
In AI inference, where a trained model processes new input, large amounts of data must be accessed in real time. Models with hundreds of billions of parameters rely on HBM to supply this data without bottlenecks, enabling GPUs to operate at full capacity. Even minor delays can impact performance, making HBM indispensable for high-end AI hardware.

Exploring the Alternatives
One potential path is chiplet-based design, where multiple smaller chips are packaged together and interconnected to share computational workloads. This setup could reduce the need for massive high-bandwidth memory by distributing processing tasks more efficiently.
Another approach involves optimizing AI models themselves, reducing parameter counts, or employing more efficient algorithms. These improvements can lower hardware demands while maintaining performance, making advanced AI more accessible and cost-effective.
Looking Ahead
If Huawei’s new inference technology can match or exceed HBM-based systems in performance, it could mark a pivotal moment in AI hardware development. By addressing both technical and supply chain challenges, such an innovation could accelerate China’s AI self-sufficiency and reshape how high-performance AI systems are built.
The details will become clear today when Huawei takes the stage. Whether this is a full-fledged replacement for HBM or a step toward easing its limitations, the announcement is set to draw close attention from the AI and semiconductor industries worldwide.
In related news, Nvidia and AMD have agreed to pay 15% of their chip revenue from China to the US. This marks a significant shift in the tech industry.
