Clovertown was basically two Core 2 Duos in a multi-chip module, and capable of multi-socket system configs. The AMD fans at the time snickered at the MCM, for being a hack and a workaround, not a "true" quad core part. AMD didn't launch the "true" quad core server part until a year after Clovertown. That was the "Barcelona" Opteron 23xx, and it was terrible, and broken. To me that was when AMD faded.
