What Is the Main Difference Between NVIDIA H100 and NVIDIA B200?
H100 and B200 are different GPU generations aimed at high-end data-center AI. H100 is based on Hopper, while B200 moves to Blackwell with fifth-generation Tensor Cores and native FP4 capabilities.
B200 increases memory from 80 GB HBM3 to 180 GB HBM3e and raises per-GPU memory bandwidth from 3.35 TB/s to as much as 8 TB/s. Its fifth-generation NVLink also doubles GPU-to-GPU bandwidth from 900 GB/s on H100 to 1.8 TB/s on HGX B200.
The practical result is that B200 is better positioned for larger models, memory-bound inference and next-generation low-precision AI. H100 remains a capable production accelerator when those Blackwell capabilities are unnecessary.
