NVIDIA A100 vs H100


In the rapidly evolving field of artificial intelligence (AI) and machine learning (ML), selecting the right GPU can significantly impact your project’s success. The NVIDIA A100 has been a staple in the industry, known for its robust performance and reliability. However, with the introduction of the NVIDIA H100, researchers and data scientists face a crucial decision: stick with the tried-and-true A100 or upgrade to the promising H100? This article aims to resolve this dilemma by providing a detailed performance comparison between the two GPUs, helping you make an informed decision that will optimize your AI workloads and future-proof your infrastructure.

Performance Metrics

Computing Power

The NVIDIA A100, based on the Ampere architecture, has been widely praised for its impressive computing power. It offers 19.5 TFLOPS of FP32 performance and 156 TFLOPS of Tensor Core performance, making it a powerful choice for AI and ML tasks.

The NVIDIA H100, leveraging the Hopper architecture, takes things a step further. It boasts a significant increase in performance, delivering up to 40 TFLOPS of FP32 performance and 200 TFLOPS of Tensor Core performance. This substantial boost makes the H100 a formidable contender for demanding AI applications.

Memory Bandwidth and Capacity

Memory bandwidth and capacity are critical for handling large datasets and complex models. The A100 provides 1.6 TB/s of memory bandwidth and up to 80 GB of HBM2e memory. This configuration has been effective for many high-performance computing tasks.

In contrast, the H100 offers a remarkable improvement with 2.0 TB/s of memory bandwidth and up to 120 GB of HBM3 memory. This increase in memory capacity and speed enables the H100 to handle even larger datasets and more complex models with greater efficiency.

Energy Efficiency

Energy efficiency is a crucial factor for data centers and large-scale deployments. The A100 is known for its relatively efficient power consumption given its performance capabilities, with a TDP (Thermal Design Power) of around 400 watts.

The H100, despite its higher performance, maintains a competitive edge in energy efficiency. With a TDP of approximately 500 watts, the H100 manages to deliver more computational power per watt compared to the A100, making it a more sustainable option for long-term operations.

Use Cases and Applications

Both GPUs excel in various AI and ML applications, but their differences can influence your choice based on specific use cases.

NVIDIA A100: Ideal for a wide range of AI tasks, including training and inference, the A100 is a versatile option for researchers needing a reliable and powerful GPU. It’s particularly well-suited for tasks that require high throughput and extensive parallel processing.

NVIDIA H100: With its enhanced performance and memory capabilities, the H100 is designed for the most demanding AI workloads. It’s perfect for large-scale model training, advanced research in deep learning, and applications requiring real-time processing and high precision.


Choosing between the NVIDIA A100 and H100 GPUs depends on your specific needs and future goals. The A100 remains a robust and reliable choice for many AI applications, while the H100 offers significant advancements in performance, memory, and efficiency, making it ideal for cutting-edge research and large-scale AI projects.
