Twice the fun!
AMD has recently released a whole range of dual core processors for the 939 socket. The high-end processors are the first to get tested, but what about the rear guard? Today I look at what we think is one of the best value processors currently on the market, the 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.

Normally the stock cooler isn't really up par when used by enthusiasts who overclock the living daylight out of their equipment, but this one seems to be the business. After further research, I found out this stock cooler and it seems to be a newer model for dual core processors. It features 4 heatpipes that redirect and regulate the thermal properties of the processor along with a fan on top to ensure maximum cooling.

The cooler does its job perfectly and doesn't make that much noise. Placing it is easy, like any stock cooler it has a spring that needs to hook up properly so it seats on top of the processor perfectly. Once the processor and the cooler have been placed properly, it's time to start up the computer and run some tests.

So all is well on the outside, but lets see how this pans out when we run some benchmarks.
