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.
|CPU core||Barton||Thoroughbred "B"||Thoroughbred "A"||Palomino||Thunderbird|
|Wafer surface (200 mm diameter)||31416 mm²||31416 mm²||31416 mm²||31416 mm²||31416 mm²|
|Die surface||101 mm²||84 mm²||80 mm²||128 mm²||128 mm²|
|Process technology||0.13 µm||0.13 µm||0.13 µm||0.18 µm||0.18 µm|
|Yield (theoretical)||255 units/wafer||306 units/wafer||322 units/wafer||201 units/wafer||201 units/wafer|
|Yield (at 60% yield rate)||153 units/wafer||183 units/wafer||193 units/wafer||120 units/wafer||120 units/wafer|
