A REPORT ON A German web site claimed that AMD is now producing such good yields on Athlon 64, Hammer technology, that it's considering canning any clock speeds lower than 2GHz when it launches next month. If the reports are correct, there might well be another reason. And that is, that despite having PR ratings for future Athlon 64 microprocessors, and despite reported problems with Intel's future Prescott chips, it's not realistic to start its desktop 64-bit family off at any speed below 2GHz, given that Intel will start that family off at high frequency speeds.

The article says AMD will introduce an Athlon 64 FX-55 at 2.4GHz (940) pins, an FX-53 2.2GHz (940) pins, a 3700+ (2.4GHz 754 pins) and a 3400+ (2.2GHz, 754) at launch time.
