Is there any indication of the speed mckinley was running at that linux demo ? How much faster was it than merced ? Muzo

< Rob, I think it's pretty common knowledge that Merced wasn't designed for the clock speed that is needed today, hence a few steppings have been needed to get it up to snuff. Takes time. McKinley, OTOH, is a newer design and clock speed requirements were taken into account more from the start. It shouldn't need those kind of steppings.> This is true as Itanium was designed with 1998 in mind. That is why even two years ago and known slippages the shout at Microprocessor Forum was: "Just wait until McKinley, it will blow your socks off!" But it wasn't always that way. Remember that Itanium/Merced was going to be an Alpha killer. If it had shown up in 1998/1999 that very might have been the case. As it is now, it is showing up in 2001 looking very much (at micro-architecture) as a 1998 CPU. McKinley and what will it cannabilize? Depends. Again, if it shows up like Itanium and slips a year or more, may not have much impact as it could be a Y2K CPU showing up in 2002 (great bandwidth and on-chip L2, McKinley will be a decent part if the compilers come up to speed). We will see! But the battle has definitely passed Itanium at this point and long denials that Itanium "isn't a pilot part" ring hollow. Rob
