When to Choose the H100

Choose the H100 for large-scale AI training and inference where 80 to 94 GB HBM3 VRAM handles models exceeding 12 GB. Its 3350 GB/s bandwidth and 1979 TFLOPS FP16 performance enable efficient processing of billion-parameter LLMs. Cloud users needing NVLink interconnects for multi-GPU scaling prefer it despite $3.14 per hour average cost.

Enterprise teams running FP8 workloads at 3958 TFLOPS select H100 for datacenter reliability across SXM5 and PCIe form factors.

When to Choose the RTX 5070

Opt for the RTX 5070 in budget-conscious gaming or lightweight AI inference with models fitting 12 GB GDDR7 VRAM. Its 40.6 TFLOPS FP16 and FP32 rates suffice for Stable Diffusion at 448 GB/s bandwidth. At $0.17 per hour average, it appeals to individual developers testing prototypes.

Power-limited environments favor its 250W TDP and PCIe form factor for quick cloud spins without high cooling demands.
