Carl, <when they put together 4 processors on the same single width memory channel, DDR should provide a significant difference.> I doubt this. For every transaction the other 3 processors must be snooped, and responses analyzed before the transaction may proceed. Therefore the FSB overhead will remain a major problem. That's why AMD seems to be moving into NUMA architectures with their Sleighammers. <how to estimate performance improvements> Yes, that's approximately what I was doing all these years, successfully predicting performance of 430XX and 440FX, LX, BX, and _other_ systems. However, there are few more tricks to this issue... Regards, - Ali
