why would any customer care about an artificial model number for an Opteron CPU based on desktop software in a single cpu mode, when their targeted application is 2-way (or higher) running server and/or workstation applications?
Additionally, SMP environments are exactly where SMT shows it's stuff best. There is no way to compare QuantaHurts with a HyperThreading system.
subzero, I think AMD's rating holds no matter what apps they use to determine it. So, the benchmark suite they'll use for the Operon may be different than the one currently in use for the Athlon.
