Will Intel Ship an x86-64bit Chip This Year?
Solid Paradox writes "According to The Register, American Technology Research predicts an x86-64-bit processor will 'soon' arrive from Intel and in another story, they also predict that Sun and IBM will be the major players in the future 64-bit boom. Meanwhile the Inquirer has a somewhat related article entitled Senior Intel PR man talks 64-bit extension talk, which follows their Pentium V will launch with 64-bit Windows Elements article that says that the chip is to be sampled internally this month."
The rumour is that Microsoft said a firm no to Intel requesting support for an entirely new 64-bit variation, but they worked out a deal where Microsoft would delay their x86-64 version of Windows until Intel was able to develop a compatible processor. The Intel x86-64 processor might even contain a few extra instructions that AMD doesn't have, just to ensure incompatibility.
These kinds of rumours may not not have anything to do with reality, but at least they can explain why Microsoft has not released the x86-64 Windows for sale even though there have been fully functional betas available for almost a year now.
Do you mean AMD64? Will the Intel chips really be fully compatible with an AMD-designed instruction set?
If this happens, it will only reinforce the fact that Intel has lost it's leadership position in the x86 compatible market. It will also severely impact any eventual large scale adoption of Itanium.
AMD just needs to bite the bullet and actually do some marketing. It has clearly superior products at this point. The Athlon 64 3000+ looks like a great buy, and a nice way to check out 64 bit computing at a low price point. If you have the money laying around, though, you really can't beat the PowerMac G5s. :-)
BTW, it's also too bad that Microsoft has delayed 64-bit Windows. It shows all too clearly that the "Wintel" partnership is alive, well, and smelly. On the other hand, it does provide a nice platform for Linux to tout it's superiority - "What's taking so long Microsoft, we've had an AMD64 version of Linux for months already!". So much for the "advantages" of Microsoft's software development practices... :-P

So, you'll have a 64-bit module sitting on top of your 32-bit CPU?
I've been speculating (here and elsewhere) that this stackable thing is not going to be Intel's next big thing. I believe that the stacked module will simply contain NVRAM and not a 64-bit coprocessor. Why NVRAM? Well, it opens up some interesting possibilities. For example, if you had enough NVRAM on-chip (or reasonably close in terms of latentcy and bandwidth), you could simply shut down portions of the processor on-the-fly to save power. You could also stick the entire operating system on the stuff. The possibilities are amazing. If you haven't looked already, see my journal for much information on the subject as it relates to Intel.
Of recent interest are some presentations by Intel on NVRAM. Of interest is that they've announced that they've found that OUM will take them beyond transistors in one presentation while another presentation actually shows a transistorless cell that is quite simple (two electrodes and a programming material sandwiched in between).
A transistorless storage device could be the piece that stacks onto the P5.

All of the posts I've read only talk CPUs. Hasn't anyone noticed that MS now (quietly) has a multi-platform software virtual machine? .NET strives from cross-platform compatibility, just as Java did years, and years ago.
MS realised this IA-32/IA-64 was going to happen, and .NET quietly solves the problem. MS is pushing people to migrate their IA-32/Win32 apps to it.
As a current .NET software engineer, the specific Windows platform becomes irrelevant.
You could easily argue that MS is delaying the 64-bit world to give developers more time to migrate to .NET.
