Even worse, all of the benchmarks that Sun throws around for these things themselves require some fairly specific configuring of certain software on Solaris, and recompiling in Forte or Sun Compiler Studio (whatever it's called now) as Sun reps have been telling you for years whenever a gcc query has popped up. Quite frankly, a lot of people decided that it all wasn't worth the hassle years ago.
In my experience Sun gear beats x86 on I/O across the backplane, not on raw processing power anymore. Also Sun's C compiler was (still is?) a factor of two faster than gcc on the same hardware (e450 with four Sparc), due to the very highly optimised math libraries Sun had made. For scientific work the Sun gear was extremely performant (although still far too expensive). Sun gear was also great as it failed very rarely compared to generic x86 stuff - which means something if you need reliability and don't have the room to do a Google (deploy large numbers of x86 boxen).
