We are moving a 70B model from H100s to B200s. How do decode latency and throughput change, regime by regime?

The datasheet ratios are close to each other, so the lazy answer is one speedup for everything. The answer splits it into three regimes, and the biggest win turns out to come from capacity, not bandwidth.
