Watts in TDP are not the same as watts in electricity, although they're both measures of energy.

TDP is a thermal measurement, it's how much heat energy your heatsink and fan need to be able to dissipate to keep the unit within operational temperatures. It does not directly correlate to the amount of electricity consumed in operation.

I know, but it should be roughly correlated and only serves as comparison for wildly inaccurate napkin math anyway.

It’s close enough. Computers mostly make heat with some math as a distant second.
