AMD's fastest Phenom FX should be branded as Phenom FX80, and all future FX8x names should be reserved for Barcelona / Budapest-based quad core parts.
The Phenom FX is the show piece that should be able to compete with Intel's Penryn 3.0GHz, but the way it looks currently, Intel's quad core stands a better chance due to its clocking and SSE4. 3.0GHz versus 3GHz would be more interesting competition, but this won't happen until Q1; and at the same time Intel plans to introduce QX9770 with 3.2GHz clocking and FSB 1600. This one will make AMD work hard for its money once again.
Both Intel and AMD know that this is now where the money is, in 2.4 or slower parts. This is the sweet spot, and they will probably start a new price war in this particular segment.
Even if Intel wins the high end competition it won’t be safe in the 2.4 vs. 2.4GHz fight, and this one might be a tough one.
