Details On The Athlon XP 2800+/2700+
The top model for January 2003: Athlon XP 2800+.
Details about the AMD Athlon XP 2800+.
After considerable discussions and simulations, AMD has finally made it: the FSB clock of 166 MHz has become reality. The chip manufacturer can now offer processors exclusively for the new clock speed, starting with the Athlon XP 2700+. Compared to its predecessor with 133 MHz FSB, the clock speed and bandwidth of the new processor are increased by almost 20%. This gives you 2.6 GB/s (166 MHz x 64 Bit x 2 flanks = 2.6 GB/s), as opposed to 2.1 GB/s.
|CPU core||Thoroughbred "B"||Thoroughbred "A"||Palomino|
|Wafer Surface||31416 mm²||31416 mm²||31416 mm²|
|Die Surface||84 mm²||80 mm²||128 mm²|
|Circuit Path Density||0.13 µm||0.13 µm||0.18 µm|
|Yield||306 pieces/wafer||322 pieces/wafer||201 pieces/wafer|
Basically, the two new processors look like the other two CPUs with the Thoroughbred B core. The die surface is still 84 mm², ensuring effective heat transfer between CPU and cooler. For cost reasons, AMD does without a heat spreader. With a core voltage of 1.65 Volt and a clock speed of 2250 MHz (Athlon XP 2800+), the maximal thermal dissipation is 75.3 Watt, while that of the Athlon XP 2700+ (2166 MHz) is 68.3 Watt.
There's no change in the maximum temperature, which is still 85 degrees Celsius. The sample processor does reveal some special aspects, however: for all of the CPUs with the Thoroughbred B core (from Athlon XP 2400+ up to XP 2800+), the thermal diode doesn't work. This means that when there's a cooler defect, the motherboard will not be able to protect the CPU. A correct measurement of the die temperature is not possible.
