Too bad the inquirer was wrong... they posted a retraction today...
May looks more likely for THoroughbred, albeit it still a wait and see since it appears that, despite hte smaller contact surface and .13 micron, Tbred will only be 10% or so cooler than an XP chip.... but taking into account contact size, the Tbred is 1.5x hotter per sq mm than the xp's are.
