TDP is mostly meaningless between manufacturers. You can (usually) compare TDP within a manufacturer but even then it’s a bit dicey across generations.

Not worthless but.... note that TDP is a thermal design spec.

It's not an electrical spec. The main difference is that a chip can overclock itself to 200W on 45W TDP, as long as the overclock period is short enough to not fill up the heatsink with heat.

And it can take minutes to fill up the heatsink in practice. Heat travels slower than electricity after all, even across copper and heat pipes.

Not through diamond, which is basically a thermal short.

I want to grow a single piece diamond heat sink.

Even single crystal ones: https://www.msesupplies.com/products/single-crystal-diamond-...

All the R&D into lab-grown diamonds is meant for endgame use in computer chips, the jewelry trade is just a short-term means of financing the way there.

> which is what actually matters, why does anyone care about raw power?

Raw power determines whether games run smoothly, how fast things compile, how fast a render takes etc. The performance per watt determines battery life but for some people that isn't particularly important. I can only run the Unreal Engine Editor for about an hour before the battery runs out on my laptop (5800H/16GB/3070). The raw performance when plugged in is much more useful to me than trying to squeeze another 20 minutes out of it. Of course I prefer using my desktop for those tasks, but sometimes I need to travel or demo so laptop (with charger) it is.

It would be TSMC 3, no?
