AMD R790 Thermal Disipation

[nn_step]

I think one thing we can all agree on is, that the chipsets are getting down slowly after nVidia hit the roof (hopefully).

Secondly, you cant just calculate TDP using Icc max and the voltage. Alot, if not all of the time its for very short peaks only. The prime example is x975 vs P965.

It should also be pretty clear that this northbridge cooler cant remove 19W

In that case, we could just aswell run P-Ms with the same cooler. Or mobile C2D/Turion with alitte bigger passive too. To help compare, even VIA CPus tend to use an active cooler over 10-12W.

Well one of the nice features of thermal dynamics is that you can just make a bigger heatsink and it'll keep quiet and cool but you'll get the rollercoaster style of heatsinks that have now become popular on Intel boards. I'd also light to note that under 5w doesn't require any heatsink (unless you want to overclock it) I do however believe that 15w is going to be the high end, since a good many of their CPUs are spec'd for 65w and perform with much less power.

ROFL

SB600 is superior to NVIDIA's suckbridges, yes.. but saying it is superior to ICH7R, ICH8R or ICH9R makes me LOL. Ever compare SATA HDD performance? It's like night and day!

I know for a fact that the SB600 outperforms Intel ICH7R
