RE: ah, okay, but in my hands...
Hi zxspectrum,
Well, if you aren't simultaneously doing video/audio recording, then my tests are not necessarily directly applicable to your uses, as I always do both simultaneously.
But, as I mentioned, GarageBand itself triggers the rMBP to switch from iGPU to the dGPU, so how do you know that Logic Pro does not also do this on the 15" rMBP? Perhaps Logic Pro uses the dGPU to perform some OpenGL audio computations (too?)! I don't use Logic Pro, but I do use the Abelton Live and GarageBand, and as I stated, GarageBand does trigger the dGPU, so potentially it is using it to speed up some audio computations (or maybe it is just to speed up the display interface, but even this might allow the CPU to run at faster speeds doing the audio computations).
...just be careful...

P.S. My responses are based upon your stated main uses, multi-track recording and Handbrake transcoding. As I stated earlier, the CPU speeds are superfluous for the Handbrake, in my opinion. But the CPU speeds are important for realtime multi-track recording. Neither of these uses requires the Retina screen, on the other hand I can understand why anyone would be interested in the Retina screens, as they are awesome. I just didn't want you to make a mistake and get the 13" rMBP and not be able to use if for your stated "main uses".
