For rr I have an i7 desktop with a base clock of 4.0 Ghz, and for building I use icecc to distribute the load (or rather I will be again when bug 1412240[0] is closed).  The i9 series has lower base clocks (2.8 Ghz, and 2.6Ghz for the top SKUs)[1], but high boost clocks of 4.2 Ghz.  If I were to switch over to an i9 for everything, would I see a notable difference in performance in rr?
