H100 remains a common choice for established CUDA deployments. B200 adds memory capacity, bandwidth, FP4 support, and a newer GPU interconnect. The right purchase depends on your workload and the server you can actually deploy.
Hardware comparison
| HGX specification | H100 SXM | B200 SXM |
|---|---|---|
| Memory per GPU | 80 GB HBM3 | 180 GB HBM3e |
| Memory in an eight-GPU node | 640 GB | 1.44 TB |
| Memory bandwidth per GPU | 3.35 TB/s | Up to 8 TB/s |
| GPU interconnect | Fourth-generation NVLink | Fifth-generation NVLink |

B200's larger memory can reduce model sharding or leave more room for context and batches. Its FP4 support may increase inference throughput when the model, quality target, and software allow that precision. Neither spec sheet tells you the training time or cost per token for your deployment. Request a benchmark using the model and serving or training stack you plan to run.
Where H100 still fits
An existing H100 fleet has a clear operational advantage: compatible systems, known software behavior, and established support procedures. H100 PCIe and SXM are also different products. Confirm the form factor before comparing them with an HGX B200 server.
What to check before choosing B200
- System: OEM model, eight-GPU or four-GPU configuration, CPUs, RAM, storage, and network cards.
- Cooling: the OEM server may be air- or liquid-cooled. Check the exact chassis and rack power.
- Software: CUDA version, drivers, framework versions, and any custom kernels.
- Commercial terms: written price, allocation, delivery date, warranty, support, and freight.
The HGX B200 GPU can be configured up to 1 kW. Total server power and cooling requirements come from the full OEM system. See NVIDIA's power and cooling summary.
