True, but how many of them are R5ks for doing the hard CPU crunching? The
original design of the R5k (according to a Byte article on it) was to
make the fastest desktop machine possible on a budget. If you wanted a
better float cruncher, go for an R8k or R10k (which aren't as good
at other tasks as the R5k). Ie, specialized chips for special goals,
rather than 1 chip for everything.
I like R10ks, but I feel more at home with an R5k if I am contemplating
assembly coding. Also, R5ks, for some reason are better at video processing
and playback in the O2s than the R1?k family is.
