Why NVIDIA H100 Outpaces A100

1. Hopper Architecture

The H100 GPU is built on the advanced Hopper architecture, engineered to tackle the demands of modern AI and high-performance computing. While it builds on the Ampere foundation, Hopper introduces several groundbreaking innovations:

• Transformer Engine: Optimized for large language models and generative AI.

• 4th Generation Tensor Cores: Offering up to twice the speed of previous tensor cores for deep learning tasks.

• Dynamic Programming Accelerator (DPX): Speeds up complex dynamic programming tasks, making it ideal for advanced simulations.

2. Memory and Bandwidth

The H100 features 80GB of HBM3 memory with a bandwidth of 3TB/s, significantly outperforming the A100's 40GB HBM2e memory at 1.6TB/s. This makes the H100 a powerhouse for:

• Processing large-scale datasets.

• Accelerating AI training and inference.

• Supporting complex simulations, such as seismic analysis or molecular dynamics.

3. Multi-Instance GPU (MIG)

The H100 supports up to seven independent GPU instances in a virtualized environment, each with its own memory, cache, and compute cores. This makes it highly scalable for multi-user and multi-tenant environments, ideal for industries like:

• Healthcare (e.g., parallel genomic analyses).

• Oil and Gas (e.g., seismic data processing across multiple teams).

4. Improved Cache Architecture

The H100’s advanced cache architecture significantly reduces latency and optimizes data flow, further boosting performance for compute-heavy applications like AI training, scientific simulations, and big data processing.

5. Scalability with NVIDIA HGX

For enterprises handling massive datasets and complex simulations, the NVIDIA HGX H100 Delta platform combines up to 8 H100 GPUs into a single supercomputing node, delivering 640GB of shared memory. This system provides:

• Eight times faster bandwidth.
