Read the introduction to Roadrunner - the Opterons are
intended to be mostly used as host processors (though I
guess initially they'll be doing more than that as people
will need to do a lot of porting work), the Cell's are
meant to do most of the grunt work.
For instance with Linpack it appears they just used the
Cell to get the petaflop number, they didn't bother to
add the 49TF's from the Opterons..
