This review and this product may lose some of its intended audience and some of its unintended as well because many people will get lost in test scores alone and not focus what I feel this new CPU is all about, and that is technology advances not test scores. Let's face it the 2.2GHz barrier for AMD remains a fact as does the fact that it is still built on a .13micron design, the new twist here is its 64-Bit architecture support that is coming soon in the near future as 32-Bit takes a backseat to better and faster code. 64-Bit code is still mainly in BETA testing at the moment but it is coming and we cannot stop it.

The first buzz about the Hammer or K8 architecture came out about two years ago in 2001 and many people were very excited about the outcome of this new technology and what its effect would have on the PC environment. Not much had been changed from its previous K7 line and in order to make changes AMD had to change the way the designed their CPU. They accomplished this by making a bigger CPU die.

Intel has very suspiciously not announced a 64-bit CPU for the desktop and although the new Itanium supports 64-bit code it is targeted at a completely different market venue leaving somewhat a gap in the market although rumors speculate that Intel's code named Yamhill may fit that bill. Intel on the other hand has very secretly released a P4 3.2 GHz "Extreme Edition" that features 2MB of L3 Cache. 2MB of cache will help those users who play games and use applications that move large pieces of code and data. Internet applications such as streaming video will probably not get much of a boost, but expect to see performance increases anywhere from 2% to 20% depending on the program with this one. This on-die L3 cache is in addition to the 512KB L2 cache, giving the Extreme Edition a total of 2.5MB of on-die cache.

With Intel making this move you know that AMD must be posing some kind of threat to their vastly coveted market, I mean a secret CPU (And hey where is mine?) CPU released immediately before the release of AMD's new 6 FX-51, hmm something is afoot that's for sure. Okay so how relevant is 64-bit technology to you today with software code being almost solely 32-Bit in the Windows environment? Here is the catch of the Athlon 64-FX my friends, its ability to work in both the 32-Bit and 64-Bit operating system environment equally a thing that Intel's 64-Bit solution is rumored to have problems with as it is supposedly only 64-Bit code friendly. Will this technology leap help keep the shelf life of the 64-FX to be a lasting event, or will it just get lost in the CPU shuffle? That is yet to be seen and as 64-Bit technology takes light is where the truest test remains for the Athlon 64-FX. Read on as we evaluate the merits and performance of AMD's latest release into the PC market.
