NVIDIA H100 vs H200: What Sets the New GPU Apart?

As the AI landscape evolves rapidly, the anticipation for NVIDIA’s upcoming H200 GPU is palpable. With substantial advancements expected over the H100, which has already set new standards for AI performance, it’s crucial to understand how these two GPUs compare. Let’s dive into the architectural advancements and performance metrics to discover what makes the H200 a potentially groundbreaking release.

Architectural Evolution: NVIDIA H100 Overview

The NVIDIA H100 has been a game-changer in AI and HPC with its robust Hopper architecture. This GPU brought significant improvements over its predecessor, the A100, with higher core frequencies and advanced computational capabilities.

Key features of the H100 include:

  • New Streaming Multiprocessor (SM) Design: The H100 features an upgraded SM that enhances execution speed for CUDA threads and floating-point operations.
  • FP8 Data Type: Introducing the FP8 format, the H100 achieves faster calculations with slightly reduced precision compared to the FP32 format used in the A100.
  • Enhanced SM Architecture: The new SM delivers double the performance for traditional data types and four times the performance boost in floating-point operations over the A100.

The H200: A Leap Forward

Anticipation for the NVIDIA H200 is high, primarily due to its introduction of HBM3e memory, which brings remarkable advancements:

  • Memory Capacity: The H200 offers 141 GB of memory—nearly double that of the H100. This substantial increase allows for larger models and datasets, enhancing the GPU’s capability to manage more complex tasks efficiently.
  • Memory Bandwidth: With 4.8 TB/s of bandwidth, the H200 significantly surpasses the H100’s 3.35 TB/s. This improvement accelerates data transfer rates, which is crucial for high-throughput computations.
