Processor Specification

Our review chip is an Athlon XP 3000+ with the following specification:

Athlon XP model number: 3000+
Cache Size: L1 - 128KB and L2 - 512KB = 640KB Total Cache
Frequency / Bus / Multiplier: 2.167GHz / 333FSB / 13.0x multiplier
Infrastructure Support: Socket A motherboards
Process Technology: 0.13 micron copper process technology
Die Size: 101mm^2
Approximate Transistor count: 54.3 million
Nominal Voltage: 1.65V
Max Die Temp: 85 degrees Celsius
Typical Thermal Power: 58.4 W
Max Thermal Power: 74.3 W
Icc Typical (low power state): 7.2 A
Icc Typical (working state): 35.4 A
Icc (processor current) Max: 45.0 A

AMD will launch the Barton with a 333Mhz bus speed instead of the rumoured 400Mhz. We suspect this is more to do with the availability and cost of memory and motherboards that are capable of running at 400Mhz FSB rather that the processors ability. As processor speed is a combination of FSB and multiplier, AMD could have made the XP3000+ run at 200Mhz FSB simply by choosing an 11x multiplier instead of 13x.

We expect the new core to launch in the form of three chips

Athlon XP 3000+ 2.167Ghz / 333FSB / 13.0x multiplier
Athlon XP 2800+ 2.083GHz / 333FSB / 12.5x multiplier
Athlon XP 2500+ 1.833GHz / 333FSB / 11.0x multiplier
