No, definately not.  They are both "sun4m", but the SS10 is using an SM41,
40Mhz, 1MB of SuperCACHE.  The SS5 is using a 70MHz MicroSPARC-II with some
teeny ammount of cache (I don't remember how much right now).  I just found
a nice table of LOTS of benchmarks of sun processors (spec numbers) in a
nice format, but I can't seem to find it right now.  This is from someplace
else, but good enough, I guess.

These might be the same ones that James L quotes all the time, but I'm not
sure.  Looks like the SS5 is going to be faster on integer performance, but
quite a bit slower on the floating point side.  Even if they were swappable,
it might not be such a good idea.  I don't know which is going to affect you
more, but you could always sell the SS5 and get another proc for the SS10,
or sell both and get an Ultra 1.
