Chips become more power efficient over time so how old is that gpu? And on what node?

If you're comparing an old ass node on a desktop part to Apple's latest and greatest mobile chip the power difference would be insane. Comparable laptop apus from AMD would manage the same, although they use like 65w last I checked.

M2 is on like 4 nanometer. Clearly a desktop pc taking 42 seconds to do basic 50 iteration renders isn't remotely bleeding edge lol.
