The X2150 seems to operate within 11-25W. That's much higher than some x86 based chipsets. Some of new Intel's Core-M Broadwell mobile chips are supposed to come in a 4.5W TDP. [1] But 11W is in range of some other older laptops. These guys may be better off targeting a gaming laptop based on an i7 to ensure adequate cooling for a server-grade processor in a laptop form factor.

And it's mostly bullshit. Those laptops will either overheat, if the OEMs trust Intel with the "4.5W TDP" claim, or will be much lower performance, or they will actually have a higher TDP. http://www.extremetech.com/computing/192893-the-first-core-m-laptop-paints-a-depressing-mediocre-picture-for-intels-broadwell http://www.extremetech.com/computing/192893-the-first-core-m... Also people need to discern between actual reviews and "we've just copied all the info from Intel's PR" reviews. My link points to an actual review, yours to the latter. Also this: "the Yoga 3 Pro allows for bursts of up to -- 12W total system consumption --- however"

  Extremetech are shit. That "review" appears to be written by someone who doesn't have the actual product - it's just a compilation of other reviews.
