Haswell 84 W

You have to account that this is Intel's Ivy Bridge 'tock', not 'tick'. This is a refinement of Ivy Bridge so it has increased performance of about 10-15% CPU power, and has a major increase in the iGPU power. This big jump in performance of the iGPU comes with an increase in power needed.

After Haswell will come Intel's 'tick' - Broadwell, which will be on the 16nm process compared to IBs 22nm. Lower power consumption, and hopefully less heat... I just hope that intel don't use TIM on Haswell and go with fluxless solder.
 
The IGP will be a lot more powerful and will add to the TDP, if you don't use the IGP then the power usage of the CPU by itself will probably be similar to that of Ivy Bridge.

I forgot about this ! This may be why I was skipping haswell
 
I think Illuz is slightly confused (I don't mean that in a nasty way :p). Haswell is a 'tock', but a tock represents a new microarchitecture on an existing and proven manufacturing process (e.g., 22nm); whereas a 'tick' is usually a die-shrink and improved version of the new microarchitecture.

Sandy Bridge was a tock because it was a new microarchitecture, but Ivy Bridge is a die-shrink of that microarchitecture with some improvements.
 
Sandy Bridge was 32nm, Ivy Bridge 22nm.

If Ivy Bridge had been built on the same 32nm process as Sandy Bridge then TDP would probably have gone up because of the IGP being twice as powerful.

Haswell is going to be 22nm as well so given that it will be a slightly faster CPU and much faster GPU a mere 7W increase in TDP over Ivy Bridge is not bad at all.
