CPU Information
AMD Athlon 64 X2 6400+ is the fastest dual-core processor for socket AM2. This processor is the best socket AM2 upgrade for people who mostly play games. For 3D rendering, Video encoding and similar applications the
Phenom 4X microprocessors could be a better upgrade option. Although at this time (March 2008) the fastest Phenom 4X runs only at 2.5 GHz, it has much better performance in multi-threaded applications than the Athlon 64 X2 6400+ due to improved micro-architecture, and primarily due to quad-core design.
