Pubblicata su Xbit una interessante prova comparativa per valutare la differenza prestazionale di una CPU ai vari valori di FSB

133MHz FSB and 133MHz DDR memory
133MHz FSB and 166MHz DDR memory
166MHz FSB and 166MHz DDR memory

nella prova inoltre viene preso in esame un P4 a 2.4GHz, pių che in esame, viene tritato in diversi benchmarck, vi č comunque da dire che non č il nuovo Northwood con 512Kb di cache full speed a 533 di FSB

Conclusion
So, we saw that the performance can be improved significantly by simply increasing the bus frequency of Athlon XP processors. When we switch from 133MHz FSB to 166MHz FSB (with DDR333 memory used) the performance gain makes 7%-15%. It's a pity that AMD will never take advantage of this opportunity. And it could be of real help especially taking into account that the competition between AMD and Intel has got even tenser after Intel had introduced 533MHz bus.

However, no one can prevent hardware enthusiasts from getting their FSB to work at 166MHz, even without AMD's assistance. In this case they will need DDR333 memory, high-quality mainboard based on VIA KT333 and AMD Athlon XP processors with an unlocked clock frequency multiplier.
