Who Should Choose Each GPU?

Choose Blackwell B200 if you…

  • Need maximum CUDA/TensorRT/vLLM ecosystem compatibility
  • Need more VRAM (192GB vs 141GB) for large model inference
  • Prioritize raw FP8 throughput (4,500 vs 3,958 TFLOPS)
  • Running Frontier Training workloads
  • Running AGI Research workloads

Choose Hopper H200 SXM if you…

  • Need maximum CUDA/TensorRT/vLLM ecosystem compatibility
  • Have power-constrained data centers (700W vs 1000W TDP)
  • Working with a tighter CapEx budget (lower list price)
  • Running LLM Inference workloads
  • Running Large Models workloads

Verdict

The Blackwell B200 and Hopper H200 SXM target different priorities. The Blackwell B200's 192GB of HBM3e gives it a clear edge for large-model inference where fitting the full model in VRAM eliminates quantization overhead. For training throughput, the Blackwell B200's 4,500 FP8 TFLOPS outpaces the Hopper H200 SXM's 3,958 TFLOPS. Both GPUs use CUDA, so ecosystem switching cost is not a factor.
