Detailed Comparison

A side-by-side analysis of key factors to help you make the right choice.

NVIDIA Blackwell (B200) vs NVIDIA Hopper (H100)
Factor	NVIDIA Blackwell (B200)	NVIDIA Hopper (H100)
Inference Performance	30x higher inference throughput via FP4, 192GB HBM3e, and NVLink Switch. Holds 1T-parameter models entirely in VRAM. Winner	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. Winner	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. Winner	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. Winner
FP4 Support	Native FP4 at hardware level. Enables 2x more efficiency than FP8 without quality loss. Winner	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. Winner	80GB HBM3 per H100. DGX H100 = 640GB total. Sufficient for models up to ~70B without parallelism.
Total Score · 0 ties	5 / 6	1 / 6
