Dan, <the 16 to 32 bit transition is where Microsoft took out IBM in the software business.>

Speaking of which, how long after Intel's 386 (the first x86 32-bit processor) introduction before Microsoft started using the 32-bit instructions? Even now, Windows 98 SE has some 16-bit legacy left.

<It's not like AMD has a choice (Intel isn't going to license IA-64 to them)>

That's what Kash told me, and from that point-of-view, it makes sense. Since it seems that no one else will be extending the x86 instruction set to 64-bit, AMD is going after the passed-up opportunity.

Ref-<It may not be particularly relevant, but the 16 to 32 bit transition is where Microsoft took out IBM in the software business. IBM pushed 32 bit OS2 early and hard, while Microsoft kept its 16-bit-with-some-32-bit-extensions-tacked-on-but-it-still-runs-dBASE II windows 3.X. This is the strategy that AMD is going for. >

Your analogy is pretty flawed. Microsoft had Windows out for several years.Finaly all the software developers jumped on the Windows platform with Windows3.0 in 1990. The OS2 appeared a year or two later, and due to inept marketing by IBM an insignificant amount of software got written for OS2. Due to the larger installed base of Windows3 , software developers automatically wrote their software for Windows3.x, perpetuating the Microsoft hegemony.

Software development for the Itanium has been in progress for several years.Numerous OS's have already been ported to Itanium,and applications have already been written. Since most software will already have transitioned to Itanium by the time AMD's 64bit processor appears, the `easier transition' argument will be moot. The x86 emulation on the Itanium also weakens the `easy transition' argument. Either Intel will have to grossly fumble on Itanium, or else the AMD 64 bit will have to offer a compelling performance advantage. None of these possibilities appear likely.

I agree that AMD's choices for 64bit are limited and it is forced into a corner. Who knows something totally unexpected might come out of left field, and AMD may have a better answer for that application. The history of technology and business is full of serendipity and surprises.
