High-Flying: AMD Athlon XP 3200+ Squares Off Against Intel P4 3 GHz

Obscure Model Numbering, Continued

The third diagram again shows the percentage difference between the model numbering and the actual core clock. The Athlon XP 3200+ has the greatest gap - 31 percent.

Customers will see the CPU through different eyes. They'll assume that the "3200+" has some bearing on the chip's actual performance. As such, you shouldn't be surprised if one of your friends picks up a box with the label "3200" at the store and brags to you that he, or she, has the fastest computer.

Wafer with Barton CPUs: if everything works out right, AMD can produce 163 Barton Athlons from a single wafer, according to THG's internal calculations and data provided by experts.
