What is the difference between NVIDIA H100 and B100?

AlphaOS investment intelligence · Research and education only — not investment advice · Updated Jul 5, 2026

The NVIDIA B100, part of the Blackwell architecture, represents a significant generational leap over the H100, based on the Hopper architecture, primarily through enhanced AI performance, increased memory bandwidth, and improved energy efficiency, enabling more complex and larger AI models to be trained and deployed faster. The B100 is expected to deliver up to 4x faster AI training and 30x faster inference compared to the H100 for trillion-parameter models, integrating two Blackwell GPUs into a single package and featuring a 208 billion transistor design.

Key Takeaways

  • The B100 utilizes NVIDIA's new Blackwell architecture, succeeding the H100's Hopper architecture.
  • B100 offers significantly higher AI performance, with up to 4x faster training and 30x faster inference for large language models compared to H100.
  • The B100 features a dual-die design, integrating two Blackwell GPUs into a single package, unlike the single-die H100.
  • Memory bandwidth is substantially increased in the B100, supporting larger and more complex AI models.
  • Energy efficiency is a key improvement, with the B100 offering better performance per watt than the H100.
  • The B100 incorporates a 208 billion transistor design, a substantial increase from the H100's 80 billion transistors.
  • NVIDIA's B100 is designed to handle the escalating demands of trillion-parameter AI models and generative AI workloads.
  • The B100 is expected to be available later in 2024, while the H100 is currently widely deployed.

Evidence & Analysis

  • NVIDIA's Blackwell architecture, unveiled in March 2024, succeeds the Hopper architecture.
  • The B100 is projected to offer up to 4x faster AI training and 30x faster inference for trillion-parameter models compared to the H100.
  • The B100 features 208 billion transistors, a significant increase from the H100's 80 billion transistors.
  • The B100 integrates two Blackwell GPUs into a single package, enhancing processing power and memory bandwidth.
  • NVIDIA CEO Jensen Huang stated that Blackwell is 'the engine to power this new industrial revolution' of AI.
