H100 vs H200: Which GPU Server Is Right for Your Enterprise?

The H100 has been the workhorse of enterprise AI for the better part of two years. The H200 builds on the same architecture with substantially more memory and bandwidth. Both are excellent — the question is which one fits your workload and budget.

The core difference: memory

The H100 offers 80GB of high-bandwidth memory. The H200 increases that to 141GB and raises memory bandwidth significantly. For training and inference, this is the difference that lets the largest models run on fewer GPUs — which can simplify your architecture and reduce the amount of expensive interconnect fabric you need.

When the H100 is the right choice

• Your models fit comfortably within 80GB per GPU.
• You are optimizing for price-performance rather than absolute capacity.
• You want the most mature, widely-validated platform with broad software support.

When the H200 justifies its premium

• Your models exceed 80GB and you would otherwise have to shard across more GPUs.
• Your inference is memory-bandwidth-bound and you need higher tokens-per-second.
• Consolidating onto fewer nodes reduces your networking and operational cost.

Both live in the same server

Whether you choose H100 or H200, the surrounding system matters: NVSwitch fabric for all-to-all GPU communication, InfiniBand for multi-node scaling, multi-terabyte system memory, and the power and cooling to run it continuously. We design the full node, not just the GPU choice.
