AFAIK the UltraSPARC T1 CPU was designed with something like 
webservers or databases in mind, i.e. the floating point performance 
is probably really bad (IIRC there is only one FP unit for all eight 
cores). I don't have numbers at hand but I guess dual core Opterons 
are still the CPUs of choice for Gromacs and similar software.
