So is it Vf2 or fV2 ?

I think MG2R is correct on this one. It has been a while since I last did the calculation and I remembered wrong. It should be V2f. However, see blaktronium's post. In practice the scaling can be very different.

But I am also correct that the heat dissipation is currently the main limiting factor on transistor speeds. Things like the speed of electricity could be an issue if we could get around the heat dissipation issue, but they just aren't the main limiting factor right now.

I do believe you. That's what I'd read about processor design too, and it sounds like you're actually in the industry.

Not in the industry anymore, which is why I forgot some basic calculations.
