H200 shortage: a comparison of B200, B300, H100, and H800 alternatives

February 2, 2026 · Qubrid AI Engineering

With H200 supply falling short of demand, customers are increasingly evaluating adjacent SKUs. Here is our rubric for picking the right alternative per workload.

When to pick which

  • Frontier training (1T+ parameters): B200 / B300 — the 288 GB HBM per card and 800 Gb/s fabric-ready design are worth the premium.
  • Large-model serving (70B–700B): H100 or H800 in an 8-way node remains competitive once tokenizer optimizations are applied.
  • Cost-optimized inference: H20 or L40 — 40–60% lower cost per million tokens served than H100 for RAG-heavy workloads.

The right choice depends on your quantization strategy, batch sizes, and the compositional complexity of your serving graph. Talk to us for a tailored recommendation.
