I'm building on a two-year-old Intel Core i5-2500 quad-core machine
with 16 GB RAM, with the source, object, and tools directories on
tmpfs.  I just did a full release build with the command

    build.sh -j 6 -D /tmp/bracket/build/2014.06.22.09.48.20-amd64/destdir -R 
/bracket/amd64/test/2014.06.22.09.48.20/release -T 
/tmp/bracket/build/2014.06.22.09.48.20-amd64/tools -O 
/tmp/bracket/build/2014.06.22.09.48.20-amd64/obj -m amd64 -U release iso-image

and it took about 40 minutes:

    2433.35 real      6561.26 user      1435.98 sys

I think pretty much any recent quad-core Intel desktop or server CPU
should meet your requirement provided you don't build on a hard
disk - either get enough RAM to build on tmpfs, or get an SSD.
