Sorry if this has been discussed, I tried a search but couldnt find anything.
I'm about to buy a 15" Retina and am choosing between the 2.3ghz and 2.6ghz models. The extra 0.3ghz will be somewhat useful because I do a lot of simulation work, but its unlikely to be a big deal in practice. However what does concern me is that in the anandtech reviews of the retina macbooks, the writer speculates that the UI lag is caused by the CPU having to do work to help out the integrated GPU, and hence that having a higher clock speed should reduce the UI lag. Playing around with machines in store, I do notice that the lower clocked 13" retina macbook has substantially worse lag than the 15", which seems to be evidence for this.
However I havent seen this discussed elsewhere. Is the anandtech review right, that 2.6ghz will give a smoother UI experience?
