I'm yet to find an actual source for that figure whenever it comes up. Is it just some tech site comment section spitballing or did they actually disclose the T

  If there's a dimensioned pix of the heatsink, a bored enough engineer could calculate the theoretical degC/W rating of the heatsink, and given a presumably constant deltaT, there's your wattage. Doesn't have to be dimensioned that accurately. To a first approximation a 1% error in surface area would be about a 1% error in TDP. I'd like to see very high temp CPU technology. That would be an interesting, challenging direction for hardware tech to move. A tiny lightweight 5 deg C/W heatsink is plenty if you're allowed to run at, say, vacuum tube redhot glow temperatures. I'm well aware of the solid state physics challenges of this, that's why I think it would be very interesting to see if anyone could pull it off.

    I doubt that a heatsink on an engineering-sample test board would be sized within a 1% margin. Seems more likely they'd be error generously on the side of big.

  Neither - the 5GHz chips were rumored for a while, and the rumors always mentioned 220W TDP. Since the first half of the rumor came true, it's fairly likely the second half will too.
