 From my measurements of the Geode and the very limited "documentation" 
of the C7 I can speculate that the integer unit can have similar speed 
to the Geode clock-by-clock (but can have a better branch predictor and 
faster movsb/movsd implementation) and probably the floating point unit 
is better integrated so floating point code does not block the integer 
unit like on the Geode. So if we do not consider the 3d unit or the 
probably better flash hardware (scatter-gather support) it will have 
exactly the same speed on similar clock speeds but of course it can go 
more than 2x faster.
