AMD R790 Thermal Disipation

[dexman]

Intel's chipsets are done on 90nm ( X38/P35/P965 ) or 130nm ( 975 ).

that´s supposed to be excuse or...? it´s like saying don´t compare K10´s TDP to Penryn´s because K10 is 65nm. it´s not AMD´s fault that Intel´s chipsets are done on 90nm.

We can just look on the actual (prototype) boards:

I only see small heatsinks on the 780 boards, not 790.

that doesn´t mean anything. P35 TDP is supposed to be 16W(although I find it suspicious when power consumption of same system is lower on P965) and look what heatsinks most of the boards use.
