Vi incollo solo un pezzo di sommario...
At 2.2GHz the Opteron was able to win every test except the SPECviewperf benchmark. This increases the total from 11 to 15 out of 17. Keep in mind however that the actual 2.2GHz Opteron would not have memory running at 220MHz, and that it would be at 200MHz instead. However also keep in mind that these tests were run at Cas 2.5 for the Opteron while the Athlon and P4 had Cas 2 memory. At any rate this is a good indicator of 2.2GHz performance.
Solo 2,2 Ghz, con memorie a 200, cas 2.5 (mentre il P4 CAS 2...).

Tenendo conto che l'Athlon 64FX dovrebbe essere identico a un Opteron, senza la possibilità di fare multiproccesing, e che consuma di picco 85 Watt...
E' impressionante poi quanto guadagni tirandolo su di "relativamente" poco... con 200 mhz guadagna più di 30 frame a UT2003...
