The power states and performance per watt have gone way up too, in 2007 power gating CPUs was not commonplace, and Intel was just starting to optimize for performance per watt (especially in the low power laptop/tablet market). What vendors have done is provide computers with the same power envelope, but much more performance so they may do your calculations @ 35 watts, and then immediately cut all power to large swaths of the CPU so as to curtail power use by at least a few watts, if not 10 watts (depends on your CPU).
