All of this talk about the memory bandwidth scores beating out the Athlon because of useless non-real world available bandwidth has made me thirsty.
So is it just the RAMBUS?
Maybe not! I have DDR (not RAMBUS) RAM in a P4 1.9 GHz running an i845BG and it yields the following.....
1014/1058.
An Athlon XP 1900+ with the same DDR in an AMD 761 board yields this.....
704/773.
Is the chipset that much better? Probably not. The way the CPU uses that memory? Hmmm.....
Not that those scores mean ANYTHING in a "real world", but you've got to admit that's a pretty big spread in numbers! If the same memory is used in the two PCs, where does this discrepency come from?
