Well, to be fair there's a whole lot of things we don't know. But we do know how smartshift works and the analogy of the mountain bike is not really the best one. The interval of this the frequency "shifts" isn't in any way comparable to thermal throttling (like classic boost clocks deal with). It means within the time it takes to render 1 or 2 frames, the power shifts between the cpu and gpu (if needed) and then back to the previous state. Meaning the heavier workload takes priority. So the clock speeds are actually more stable than the theoretical speeds in current gpu architecture (due to thermals).
Let me try a bike analogy for the PS5 too, it would be like you're trying to climb a hill and instead of applying equal pressure on both legs, you shift your weight left and right, depending on which leg is doing the downward movement.
As for the XSX, the previous analogy with the car going 120MPH was pretty good, won't even touch it![]()
Actually AMD smartshift is 2ms, so its very rapid. We dont know what Ps5 does yet for smart shift and teh GPU downclock on edge case / virus type code generating heat.
I would expect its also many times a frame. Waiting for sensor to detect heat at one location on an area of a die is allot slower than deterministically knowing what causes heat before work load is processed.
