Core Viewpoint - Nvidia is planning to release a modified version of the H20 GPU, referred to as a "special version" for China, based on the Blackwell architecture instead of the original Hopper architecture [1]. Group 1: GPU Specifications and Market Impact - Jefferies analysis suggests that the US may impose a memory bandwidth limit of 1.7-1.8TB/s on GPUs, which could lead Nvidia to replace HBM memory with GDDR6 in the downgraded H20, potentially outperforming gaming GPUs like the RTX5090D [2]. - Another report from GF Securities indicates that the new GPU, possibly named 6000D or B40, is expected to be released in early July, featuring GDDR7 memory with a bandwidth of approximately 1.7TB/s, compared to H20's 4TB/s [3]. - The expected shipment volume for the B40 GPU is projected to reach around 1 million units by the end of 2025, supported by NVLink and CUDA technologies [3]. Group 2: Market Dynamics and Historical Context - Prior to the ban on H20, there were indications that it would be discontinued in favor of a Blackwell-based special version, which was not fully prepared at the time of the ban [3]. - The rapid development and release of the new GPU can be attributed to Nvidia's established design framework and TSMC's advanced manufacturing processes, allowing for a quick turnaround following the H20 ban [3].
