Paul - RE: "By that definition, the AthWipey DOES NOT HAVE a 200 MHz FSB - it has, simply, a double pumped 100 MHz FSB. Now - rationalize your way out of this !" Sure! I don't know too much about the technicals about this, but from what I have read on the net the Athlon fsb runs at 100MHz, but data is sent on the rising and falling parts of the path (whatever that means ;) ) or something like that and is therefore not double pumped and it can be called 200MHz. And this is the same way DDR SDRAM is double the speed of normal SDRAM. I think DRDRAM may be like this also because it is called PC800 but it runs at 400MHz. I don't know if Willy's 400MHz bus is a quad pumped 100MHz bus or a double pumped DDR 100MHz fsb. Here's what Elmer says about double-pumped - "The interesting point is the reference to AGP, obviously meaning the double-pumped nature. While AGP2 runs at 66MHz it performs 133 Mega Transfers. So what if you technically can't call it 133MHz it still performs the same as a transfer operating at 133MHz off the leading edge of the clock. So it looks as though the ALU doesn't have a 3GHz clock but it still operates the same as a 3GHz clock which is only active on the leading edge. The end result is the same. 3 Billion operations."
