Ivy Bridge 2.0 GHz i7 vs Broadwell i5

[Cicatrix]

Coming off a 2012 MBA with 2.0 GHz i7, how much faster would a soon to be released 2015 MBA with a Broadwell i5 processor be? I would like to save a few bucks if I could get away with it.
Currently my MBA handles all my music apps like Reaper/Logic just fine for my projects. So I would think the Broadwell i5 should be just fine. I guess?

Clock-for-clock, Broadwell should be a small percentage faster.

The bigger difference for you is that the 2012 MBAs get too hot to turbo boost, so if you're doing sustained CPU operations (e.g., using Handbrake to transcode video or something like that, for several minutes at a time) then Broadwell might be up to twice as fast.
