A DEC study from a couple years back demonstrated that Alpha
binaries were on average 25-35% larger than their x86 cousins. This of course
was conducted under Digital Unix with their optimizing compilers, so read those
stats with a grain of salt. Comparatively, figures like 25-35% are quite
good compared to the traditional "RISC factor" (ie. the penalty for reduction
of instruction set) where 50% and larger are not uncommon.
