Quick Verdict
Detailed Comparison
A side-by-side analysis of key factors to help you make the right choice.
| Factor | NVIDIA Blackwell (B200)Recommended | NVIDIA Hopper (H100) | Winner |
|---|---|---|---|
| Inference Performance | 30x higher inference throughput via FP4, 192GB HBM3e, and NVLink Switch. Holds 1T-parameter models entirely in VRAM. | Good inference performance in FP8 and FP16. Production deployment standard 2023-2025. Proven and broadly available. | |
| Training Performance | 2-4x better than H100 for modern architectures via second-gen Transformer Engine. | Market standard for LLM training 2022-2025. Well-suited for models up to 70B parameters on single node. | |
| Energy Efficiency | Significantly more efficient: FP4 enables 4x more operations per watt. | Good efficiency for its generation, but significantly less efficient than Blackwell. | |
| Price and Availability | More expensive (B200: >$30k), limited availability in 2025. Long-term cheaper through efficiency gains. | Lower spot-market prices due to larger supply. H100: $25-28k, broad cloud availability. | |
| FP4 Support | Native FP4 at hardware level. Enables 2x more efficiency than FP8 without quality loss. | No native FP4. FP8 as lowest precision tier. INT4 possible but with latency overhead. | |
| Memory Capacity | 192GB HBM3e per B200 chip. GB200 NVL72 = 1.4TB total. Enables 400B+ parameter models without model parallelism. | 80GB HBM3 per H100. DGX H100 = 640GB total. Sufficient for models up to ~70B without parallelism. | |
| Total Score | 5/ 6 | 1/ 6 | 0 ties |
