I'm sorry to ask, but don't you rather mean watts than watts per second?
There may indeed be a second order time component involved - for instance, a
cooling system that can handle 10 watts continuously, 20 watts for up to 30
seconds, or 40 watts for 10 seconds max. And of course, "40 watts steady for 10
seconds" is different from "averaging 40 watts but bouncing between 30 and 50
watts for 10 seconds" etc etc..

And of course, there's usually a per-system limit, and per-chip limits, and
your power/cooling budget constraints may force you to go for a higher value
on one to make the budget for the other (burn an extra 0.5 watts in chip A
in order to get Chip B under 0.87 watts type stuff)....
