Review: AMD Athlon 64 4400+ X2 |

It seems Moore's Law refuses to go quietly into the night. When the
engineers at Intel and AMD saw that clock speeds were hitting a wall and
that any additional increases would require ever more exotic cooling
solutions to deal with the power requirements and subsequent heat,
their beady little eyes (from staring at all those microscopic
transistors of course) turned to multiple cores. As odd as it sounds,
dual cores use less power and, as a result, produce less heat. The added
benefit to multitasking doesn't hurt either, and will be something we
will take a closer look at in this review.

The AMD Athlon 64 4400+ X2 is part
of AMD's new line of dual core processors which promise to offer you the
capability to truly multitask. AMD's
dual core line puts two physical cores on a single chip with a direct connect
which allows them to efficiently communicate with each other. AMD decided to ditch the standard FSB
architecture in favor of the new direct connect architecture which helps
alleviate some of the problems and bottlenecks inherent in the processor. AMD has designed their new dual core
processors to use the same pin layout as other 939 processors which means only
a bios upgrade is required to take advantage of the new processors. The downside to this is that AMD is still
using the same memory interface which is now being shared by two cores.
The X2 series of processors from AMD
also uses the same benefits of AMD64 technology which includes Hyper
Transport Technology, Enhanced Virus Protection, AMD's Cool'n'Quiet
Solution, and the
ability to use 64-bit applications. Normal logic would dictate that the
addition of a second core would
almost double the power required by the processor. This is not the case
at all, and AMD's X2
will even run cooler than a single core processor on a higher
manufacturing
process. In addition, the availability of two separate cores offers
enhanced
performance with multi-threaded applications such as 3DSmax, as well as
the
ability to multi-task by running multiple applications at the same time
without
much of a performance hit.
As you can see in the image above,
the X2 series has two separate cores--each with its own L2 cache. Each core is connected through the system
request interface which will direct request for resources to the appropriate
core. For your reference below, we have
included a table with some basic information about the processors in the X2
series.

AMD Athlon 64 X2 4400+
Socket type: Socket 939
Core: Toledo
Frequency: 2.2GHz
HT: 1GHz
L1 Cache: 2 x 128KB (128KB per core)
L2 Cache: 2 x 1MB (1MB per core)
Process: 90 nanometer
Instruction Sets: MMX, SSE, SSE2,
SSE3, 3DNOW! Professional
Voltage: 1.35 - 1.4V
Wattage: 110W
One thing I would like to note is
that while looking on AMD's site, I noticed they also list a 4400+ with wattage
listed at 89W. Apparently, the OPN
code for the 110W version is ADA4400DAA6CD, while the OPN code for the 89W is
ADV4400DAA6CD. The version that we have
for testing is the 110W version.
