Choosing the Right GPU for AI and HPC
As the popularity of AI and machine learning continues to grow, organizations across various industries are investing in modern GPU servers to enhance their AI and high-performance computing capabilities. Determining which GPU is the right fit for your workloads can be challenging, but the H100, NVIDIA’s most popular data center GPU, provides a great starting point.
Comparing the NVIDIA H100 PCIe and SXM5 Form Factors
Choosing the right form factor for your NVIDIA H100 GPU can have a significant impact on the performance and scalability of your server. Both options have their own advantages, so let’s take a closer look at their features to help you make an informed decision.
H100 PCIe Overview
H100 PCIe is a traditional GPU design that connects directly to the motherboard through PCIe slots. These graphics cards are available both individually and as part of servers with up to 8 GPUs. This form factor offers ease of installation and flexibility, making it suitable for various server configurations. However, the PCIe interface can introduce latency and bandwidth limitations, affecting performance in demanding applications.
H100 SXM5 Overview
H100 SXM5 is a more integrated solution that combines GPU, memory, and other components into a single module with 4 or 8 graphics accelerators. This design reduces latency and increases bandwidth, resulting in higher performance for compute-intensive workloads. The SXM5 form factor also supports NVLink, NVSwitch, and InfiniBand technologies, enabling seamless integration into large server clusters for large-scale AI tasks.
Performance and Cost Comparison
The NVIDIA H100 GPU outperforms its predecessor, the A100, by up to 10x on AI workloads. The SXM5 model takes it even further by supporting 80GB of fast HBM3 memory and delivering over 3TB/s of memory bandwidth, which is 2x the capacity of the A100, released just two years earlier. The H100 PCIe provides 80GB of fast HBM2e memory with over 2TB/s of bandwidth.
In terms of performance, the H100 SXM5 form factor outperforms the PCIe variant due to its integrated design and support for advanced networking technologies. While the initial cost of SXM5 servers may be higher than PCIe-based systems, the long-term benefits in terms of performance and scalability often outweigh the initial investment.
NVLink, NVSwitch, and InfiniBand Networks
NVLink and NVSwitch are cutting-edge technologies that allow multiple GPUs to communicate directly at high speeds, enabling efficient parallel processing in large server clusters. SXM-exclusive NVSwitch and InfiniBand technologies further enhance processing capabilities by providing high-speed connections between servers, allowing for seamless scaling of infrastructure for AI tasks. Creating an infrastructure with H100 SXM5 GPUs and InfiniBand networks allows you to build a data center-scale GPU, enabling you to quickly solve even the most complex AI tasks.
Industry Standard and Availability
It is worth noting that 8-accelerator H100 SXM5 systems are currently the industry standard for large organizations and AI startups due to their superior performance and scalability.

Conclusion: PCIe vs SXM5 – Which to Choose
In conclusion, both the H100 PCIe and SXM5 form factors have their own advantages and limitations. While PCIe offers flexibility and ease of installation, SXM5 provides superior performance and scalability, especially for large-scale AI tasks. ITGLOBAL.COM recommends considering the SXM5 form factor for your NVIDIA H100 GPU, as it represents the current industry standard for performance and scalability.
