 last year the target speed was 1.5ghz, 4 cores.  this time we
envisage 8 cores at over 1.2ghz, and the cores can be made to support
VLIW which can result in 3x the effective clock-rate.  so i don't
think that CPU horsepower is something to worry about.  the only thing
that's of concern is to not put too _much_ horsepower down so that it
goes beyond the gate-count budget.
