Intel's quad core is out already, although you coud argue it's not a "true" quad core, just 2 Core 2 Duos stuck together
AMD will have the first real quad core
The back and forth of superiority is the same with video cards, at the minute nVidia is on top with the 8800GTX, but then ATi (or DAAMIT as it's now called) will take back the top spot with its next release, then nVidia will beat it...ad infinitum
@linuxlover - The FX-62 runs at 2.8GHz, it is essentially 2 FX-57s
It is still a powerful chip, but it has nothing on the Core 2 Duo
AMD's model numbers don't relate to the actual chip speed, see here -
