Athlon 64 X2 4400+

The AMD Athlon 64 X2 dual-core processor puts the power of dual-core technology on the desktop. Dual-core processors contain two processing cores residing on one chip. They perform calculations on two streams of data, thereby increasing efficiency and speed while running multiple programs and the new generation of multi-threaded software. Even against the fastest single core Athlon 64 processors, the X2 can outperform them by an enormous 40%. Both cores have their own separate Level 2 cache of 1 MB, but they share the system request queue and crossbar whichs means that both cores can work separately. They also share the same memory controller. The beauty of these processors is that they can make use of existing sockets and still expand your performance envelope...
