In number crunching SAM 460 is barely as fast as the Pegasos2 G4@1GHz if you don't account for the altivec. If altivec is taken into account then G4@1GHz runs circles around the system. Granted, Sam460 has a faster memory interface, but the number crunching figures are quite disappointing.
Why is it that it's so hard to find SPECint and SPECfp figures for AMCC460? AMCC appears to only quote some DMIPS values which frankly are quite useless.
I would have expected a new HW to actually surpass the 6-7 year old one, especially considering the extremely high price of the system. Sam 440 systems were already pricey but this 460 takes it to a new level (900 eur).
Just because something is "new" doesn't make it better anymore.
