ICC can produce faster code, but it won't always... It tends to be about 5% faster on my own path tracer. One thing to note is that there are several compiler options for optimization. There are things like global interprocedural opts, even interfile opts, and you can also compile using statistics from previous runs (to aid branch prediction, etc...).
I would say that most of the time, ICC produces slightly faster code. My argument is that GCC can do things from the C++ standard that ICC cannot, like partial template specialization.

What is exactely the benefit of ICC ?
It produces _much_ faster code than gcc (even the very latest 3.4-stuff) for most applications I have tested.
I just testet it with povray. The gcc compiled version of povray is faster than the icc version.
These are the scenes I tested:
/usr/share/povray/scenes/balcony/balcony.pov
gcc: 125s icc: 190s
/usr/share/povray/scenes/abyss.pov
gcc: 23s icc: 23s
So I don't think, that icc produces faster code.
