AMD launched its Athlon 64 family today, unveiling the 2GHz Athlon 64 3200+ for consumers and similarly clocked Athlon 64 FX-51 for 'pro-sumer' customers seeking that little bit extra.
The difference between the two chips: the FX has a built-in dual-channel 128-bit DDR controller, while the 3200+ connects to a single-channel 64-bit memory bus. The latter works with unbuffered memory, the former with registered DIMMs.
