h100

On paper an H200 SXM is an H100 with more and faster memory, so nothing should get slower. The answer works through the four ways it can anyway, from the spec sheet you did not read to the tuning table that does not know the new device's name.

Counting GPUs across two generations gives the wrong plan, and routing by GPU count breaks the SLO on the slower pool. The answer defines one capacity unit at the SLO, then plans, routes and buys in it.
