The Wii U has more ram, thats it. Everywhere else it is lagging. You obviously do not understand the correlation between semiconductor lithography and power consumption.

Wii U : 40/45 nm & 40 Watts

PS360 Slim Versions: 40/45 nm & ~100 watts

Do the math.

Care to elaborate more? I'm led to believe that technology is supposed to become more effiecent over time.

Chip designs get more efficient over time, but engineers are not wizards. Especially when it comes to GPUs, where things are highly paralellized. You can improve a design and gain maybe 15% performance under the same thermal ceiling. You can't ever get 100%. Ever seen a 100W AMD card beat a 200W nVidia card? When both cards are in the same proccess node, it cannot happen. Also consider that the GPUs from all 3 current gen consoles, come from the same fab(TSMC).

not really true because smartphones are approaching ps3 power and they draw like a watt or two.

 

i am very certain even a ps360 manufactored on 28nm couldn't approach that.

 

mind you, i believe the wii u is quite weak. just correcting you.
