[FONT='Verdana','sans-serif']Although they're hard at work on Barcelona and plan to release a new high-end, native quad-core CPU in the coming months, AMD has turned a good part of their attention to a different segment of the market, the low power segment. Back in August of 2006, AMD released several low power CPUs that aimed to balance performance and power consumption. One was the 'Windsor' based Athlon 64 X2 4600+ with a TDP of 65w and the other was the Athlon 64 X2 3800+ which had a low TDP of 35w. While the processors were impressive from an efficiency standpoint, AMD struggled to keep up with demand and also offered the models at premium price points. In February of 2007, AMD changed their approach somewhat, introducing its "Brisbane" core. The new 65nm Athlon 64 X2 processor came in a smaller package and dropped maximum power requirements from 89w with the "Windsor" cores to 65w with "Brisbane". Furthermore, the more power efficient processors were released in mass quantities, with no additions to the price structure.
[FONT='Verdana','sans-serif']Today brings us to the next step of AMD's low power strategy, with the release of AMD's 65nm Athlon X2 BE-2350 and BE-2300 processors. These 'Brisbane' based models sport a maximum power rating of 45w and weigh in below $100, making for a cost effective processor that is cheap to buy and cheap to run. The cores of these new processors are still 'Brisbane' based, so there isn't a lot new here to go over as far as their architectural characteristics go. However, as you can see, AMD did find it the right time to introduce a new numbering scheme in an effort to more accurately represent a processor's features and performance.
