So why 6000+ and not FX-64? All previous top end Athlon 64s for
the desktop had the FX moniker, so why the change? The answer to that is
with the FX-7x series of chips. AMD wants to keep the FX name to its very
top end enthusiast oriented products. In this case the FX-74 is the very
top end of the new “mega-tasker” niche. AMD feels that the no-holds
enthusiast should be the only ones sporting the FX label. So this has left
the single socket crowd without a FX product. For the time being at least.
When native quad core AMD products are released, it appears as though there
will be another FX based product for the AM2/AM2+ socket.
