AMD Athlon XP and 166MHz FSB article

Good find. If AMD wouldn't lose yield and have the ability to do it then it would be more than worth it to do it. But the lower yield would probably push the prices up a bit if they did.
 
other than possibly warmer system components, the process would not be running hotter at 166fsb than 133fsb if they are the same voltage.

Increasing FSB speeds could also reduce the yields AMD gets on .13-micron Athlons. Obviously this is the last thing AMD wants to do. In addition, I don't think the performance gains from an increased Athlon FSB would be that substantial to begin with, making any investment in the marketing, selling, and validation of 166MHz FSB Athlons illogical.
 
I wouldn't be surprised if AMD sits on this for a while, leaving the Hammer for the highend, and the Tbred/Barton as the Duron for the near future. Should this new "Duron" begin to lag in peformance against the Celeron, AMD could push up the FSB to compete more closely with Intel.

Why? does the increased fsb speed (6ns) mean more chance of noise than say a qdr system as with intel? I am not clear on how this would effect amd's processor yields rather than the motherboards yields.
 
Gains depend on the tests. With 0-6% I agree, not worth it this late in the Athlon cycle. At 8-15% maybe, but I tend to lean towards's Anands tests and conclusion

But Anand was using a KT266A-based motherboard, not KT333.
