I still think that will be Itanium IA-64, not some new Yamhill IA-32-64. Unfortunately for Intel, the "affordable" 65 nm IA-64 will perform like a Celeron compared to 65 nm dual Opterons and be roughtly equivalent in cost and performance to a 90 nm Opteron. Itanium's performance per transitor is just low. I do think the Prescott with extra pins that comes out mid-2004 probably has some kind of segmented >32-bit addressing. Or maybe the extra pins are just direct DDR and DDR II interfaces, i.e., memory controller on-chip. That would take away one of Opteron/Athlon 64's advantages. <I think Intel will have to reveal its cards in September, to undermine adoption of AMD64.> They will probably yell a little louder about higher clock speeds, and higher memory bandwidth, at least vs. Athlon 64. They can give big incentives for software companies not to optimize for AMD-64. And they can make server chipsets that support 40 bits of memory address space with 32-bit segments. Microsoft must already be supporting something like this for Xeons. (or maybe it'll be "in-the-chip"} <I wouldn't be surprised if [in September] they started emitting some vapor about the IA-32-64 beast, so that third parties don't invest in AMD64 support. I am surprised that Intel has not done it yet.> The fact that they haven't, or that we haven't heard a peep about anyone writing code for a Yamhill instruction set is the main reason I dis-believe it is currently in their plans. But you are right -- they could announce it in September to kill support for AMD's solution. Of course, they would promise chips for 2004 and they would actually arrive in 2005 at the earliest. But Mickey and Carly would probably believe them. If we don't hear anything about Yamhill around AMD's September launch, then I think you'd have to agree that Yamhill is dead, dead, dead. Petz
