Intel measure average TDP whereas AMD measure absolute maximum TDP and thus Intel come to strange TDP numbers such as 77 and AMD come to higher ones.
I am excited to see the performance of these chips as they are an indication of the next FX series.
Quoted for truth!
Finally someone got TDP right, always irks me how people think TDP = Power and that automatically because the 5800/6800k are listed as 100W TDP that they draw tons of power and require massive heatsinks at stock clocks. My old Intel i7-920 was listed as 130W TDP, and I assure you that even before overclocking it used far more than 130W of power and under 100% load needed more than 130W of thermal dissipation. The 130W listed was for what Intel considered "average" loads.
