Model Number Comparisons

The introduction of the AMD Athlon™ X2 dual core processor BE-2350 and BE-2300 brings the first opportunity to learn about AMD’s new model methodology. The goal with the new system was to better inform processor choice and utilize a methodology that be long lasting. Existing products will retain their current model numbers. Our customers are familiar with the current models and we will continue to utilize that system until it is phased out over a period of time by new product introductions. New AMD desktop processor models have an alpha numeric format.

Let’s look at a sample model number: BE-2350

First two characters: BE-2350
The first and second alpha indicate the processor class. The second alpha character indicates the TDP of the processor. The “BE” class is comprised of sub-65W processors. This chip’s TDP is 45 watts. As additional products are introduced, new classes will also be introduced to distinguish between major processor attributes.

First numeric digit: BE-2350
The four digits are the processor model within a class. The first numeric digit after the dash is the processor series and reflects major increments in processor attributes. The “2XXX” series is currently contained within the AMD Athlon X2 family of processors.

Last three numeric digits: BE-2350 The last three numeric digits after the dash indicate the relative position of the CPU within its class series. Increasing numbers within a class series indicates improvements in processor features and attributes.

In summary:
Just by reading the “BE-2350” model number, you know that it is a mainstream desktop CPU. You know its power consumption level is below 65 watts. You know that it is in the Athlon X2 family. And you know its position relative to other CPUs employing AMD’s new model number system. As new processors are introduced, the combination of class and models should be of increasing value in identifying and distinguishing AMD processors. Previously, our model numbers indicated relative performance but were unable to capture the step function performance multi-core processors in many usage processors. The chart above lists available AMD Athlon 64 processor models, corresponding processor frequencies, and associated features.
