I dont think Intel or Nvidia got the memo on this. Both are pumping out seemingly more and more desparate products where their solution to more performance is just to throw more power at it, causing obscene levels of heat in the process.
Meanwhile down at the mid-end you've got Apple chipping away at them with ultra efficient ARM chips.
what? the 4x series cards are the most energy efficient graphics cards ever made. ignore the 4900, they just scaled the top end to have high power and high performance. look at the low tier. they all have significant power requirement reductions compared to the 3x cards. watts per fps is down
