As a result of the announcement that will presumably happen next month, AMD’s Athlon 64 lineup will catch up with the Athlon 64 FX-51 processor in terms of clock-speed. Its performance is still to be confirmed, however, as the FX-family of microprocessors from AMD have one tangible improvement over the ordinary Athlon 64 chips – the dual-channel memory controller.
AMD Athlon 64 processor in Socket 754 form-factor designed for performance-mainstream and high-end desktop computers sports 128KB of L1, 1MB of L2 and single-channel PC3200 memory controller. The Athlon 64 FX has dual-channel memory controller and is able to pump in more data at once, eliminating a system bottleneck.
Currently AMD ships Athlon 64 processors clocked at 1.80GHz and 2.00GHz for desktop or desktop replacement notebooks. The only available AMD Athlon FX – the FX-51 chip – functions at 2.20GHz, even a bit faster than its “non-FX” brethren.
