The "Black Edition" of AMD's Athlon 64 X2 5000+ features an unlocked multiplier. Unlike the first Black Edition model, the 90nm 6400+, the new processor is produced on a 65 nm process. As a result, it only draws about half as much power as the 6400+, and offers enormous overclocking potential. Pushed to its limit, this processor is faster than an Athlon X2 6000+ or Intel's Core 2 Duo E6550. Among today's CPUs, this $130 processor is unique in that its performance can be increased without having to raise either the FSB or the memory frequency, making it a safe choice for any AM2 board.
