You're going to compare a CPU with 7 times the TDP against an ultrabook CPU? AMD doesn't have anything in the ultrabook premium space to compete against Haswell U.

Well AMD's and Intel's TDP are not identical and it does not indicate power consumption.

i5 3317U has a TDP of 17 watts while it consumes40-50 watts at full cpu and gpu load then add 2-4 watts for on-board FCH.

Looks impressive.

Amd needs to turn it up another notch.

not where you got that number from (source?)

Run any 3D game where the GT cores have to work and the story changes dramatically. The CPU cores at 100% load and 2.8GHz consume around 15W of the allowed 17W TDP, but the GT cores under load appear to be capable of drawing 10-11W. Try to use them both at the same time and what follows is a balancing act (i.e. throttling) in order to stay within the allowed power and thermal envelope. The CPU package does manage to exceed the 17W TDP for a time, but after seven or eight minutes it drops to 17W before eventually stabilizing around 15W (±5%).

to fully utilize both the CPU and GPU without throttling, you're looking at...

you’d need a 25W TDP in practice—around 10W for the HD 4000 and another 15W for the CPU cores

Not just in wattage power, but in cooling capability. Most ultrabooks can't cool anything close to 25 TDP without sacrificing its thin form factor.

So I don't know where you're getting this 50 watts from.

15w haswell have much better battery life than 17w ivy bridge
