The NVIDIA H100, also known as Hopper H100 Tensor Core GPU, is equipped with 80 gigabytes (GB) of HBM3 memory. This high-bandwidth memory is essential for handling large datasets and complex AI models, and the H100 is designed to deliver unmatched performance for AI and high-performance computing (HPC) workloads. With 80GB of VRAM, the H100 is able to tackle some of the most memory-intensive tasks in areas such as natural language processing, drug discovery, and more. It's important to note that NVIDIA might offer different configurations of the card in the future, so it's always a good idea to check the latest specifications directly from NVIDIA or from trusted industry sources.
