The AMD Athlon 64 X2 Dual-Core Socket AM2 processor puts the real power of dual-core technology on the desktop. Dual-core processors contain two processing cores, residing on one chip, that perform calculations on two streams of data, thereby increasing efficiency and speed while running multiple programs and the new generation of multi-threaded software. These new AM2 socket versions support DDR2 memory modules designed to improve overall memory performance through increased bandwith and larger densities. For the end-user this means a significant increase in response and performance when running multiple applications simultaneously. The AMD Athlon 64 X2 Dual-Core processor outperforms the highest-performing AMD Athlon 64 4000+ single-core processor on multi-tasking benchmarks by up to 30%. Digital media software demands simultaneous processing of data streams, the perfect use for the incredible multi-tasking power of the AMD64 dual-core technology. Dual-core technology is like having two processors working together, each one taking care of different applications, so power-users actually experience greater performance when multiple applications are running.
