Reuters reports that Samsung is facing challenges with its latest HBM3 and HBM3E memory stacks. They have failed Nvidia's tests due to excessive heat and power consumption issues. This setback is significant for Samsung as Nvidia dominates the global processors market for AI applications. But this could be an issue for Nvidia, which needs all the HBM supplies it can get to meet the demand for its processors based on the Hopper and Blackwell architectures.
Formally, Samsung's HBM3E memory stacks are the fastest in the industry, rated for data transfer rates of up to 9.8 GT/s/. Samsung officially started production of its 24 GB and 36 GB HBM3E in late April. However, the report from Reuters says that without elaboration, some of Samsung's HBM3 and HBM3E devices cannot pass Nvidia's validation for specific products.
