In what way, precisely? As posted above, I find that my new 2.8GHz i7 QC machine gets through a Vivado run about 20% faster than my old C2D @ 2.5GHz (i.e. 2.5hrs rather than 3hrs on the old machine).
About the only thing that is very much better on the new machine is its 4K resolution display (compared to 1440x900 on the old one).
Oh, and the new machine can handle SD cards of > 32GB.
Thanks to the crap trackpad and chiclet keyboard on the new machine, I tend to prefer _using_ the old one.
