      Compaq purchased DEC, and halted the Windows2000 production agreement with Microsoft. Microsoft regretably pulled support from the Alpha in RC1 of Windows2000.

    I recently built a Dual Xeon (with EM64T extensions) machine, and I tried Windows XP x64, and it is running pretty well so far. It is backwards compatible with 32-bit applications, but you need to find 64-bit drivers for your hardware. 32-bit drivers will not work.

        You are simplifying things a bit, but in a round-about way it is true!

        From Redhat's release notes for the update 2 to RHEL3.

        Software IOTLB -- Intel® EM64T does not support an IOMMU in hardware while AMD64 processors do. This means that physical addresses above 4GB (32 bits) cannot reliably be the source or destination of DMA operations. Therefore, the Red Hat Enterprise Linux 3 Update 2 kernel "bounces" all DMA operations to or from physical addresses above 4GB to buffers that the kernel pre-allocated below 4GB at boot time. This is likely to result in lower performance for IO-intensive workloads for Intel® EM64T as compared to AMD64 processors.

        See for yourself:

    • And this seems to be the big problem at the moment.

      I don't know about you, but I certainly haven't been seeing optional 64-bit versions of drivers anywhere.
    • Yup i found the same issues with my athlon 64 too. Another big big problem. SATA support is still not in natively. So you have to use the CD provided by the manufacturer. So if you build a brand new system with SATA, best of luck if you dont have the drivers on a floppy. Installation says press so and so key if you have SCSI/RAID drivers and then if you do so looks for them on floppy. Then there were some other bugs like wallpapers acting funny and all. I didnt really see a huge performance dip in Windows
      • So to use modern harddisks with Windows you need an antique floppy drive most of us haven't used for years?
        • Yeah, that's pretty much it. I would have thought that winXP64 would have included SATA drivers, but nope, they aren't included. It would have been nice if they had of at least made it possible to grab them of a usb keyfob/thumbdrive/whatever you wanna call 'em. I mean, c'mon, I can boot a full Linux distro off one of those things. I expect windows could have at least been able to grab some drivers off 'em.

    I recently upgraded to an Athlon64 3200+ and downloaded the Win64 eval/beta. There's practically no difference between it an Windows XP. I hvaen't had a single weird application incompatibility -- it's running all my 32-bit stuff just fine. I'm a gamer, so "32-bit apps" includes some hefty 3D-accellerated, DirectX-using stuff. I don't have any 64-bit apps to test with.

With RC1, Microsoft has finally turned off debugging and cleaned up the memory management code so that memory usage is more or less exactly in line with XP32(the previous Beta builds ate memory like Roseanne Barr at a buffet), and ZDNet has a good point about the driver stuff, since RC1 includes support for such new stuff as ATI's Radeon X-series cards right out of the box.

I've only had it up and running since just 2 weeks prior to christmas, and have had no major hiccups so far. I have concerns about the speed and availibility of service packs and drivers (as in with such a small niche of customers having these processors will Microsoft, and more importantly 3rd party software and driver venders be as dilligent in keeping them updated, prior experience says no) Still It feels faster than having it run XPpro x32. AND it was free for the beta testing, SO, I've got like 340 more days of free OS action to keep me going.

    In a Classic sense, right next to the AMD sits an Original, |D|I|G|I|T|A|L| Alpha thats currently running NT4 for Alpha and Gentoo (Though it started out with Red Hat). Running NT4Alpha is one of those things that you never forget. Its fast, stable and relatively virus proof but the biggest problem with it is the LACK OF APPLICATIONS. There were and are no third party apps compiled for NT4Alpha. this was such a major issue that |D|I|G|I|T|A|L| released an emulator thingie, but even that was too little too late to save it.

    Thankfully, AMD decided to include Backwards compatibility on the die. because doing it at the higher level chalks up some major performance penalties. But lest we forget, liscensing Alpha technology is the reason we have a lot of the "innovations" boosting speed as of late *cough* Hyperthreading *cough*

    Well, this is disappointing. For the first time ever Microsoft is dropping support for binaries that ran in earlier versions of Windows.

    Does Microsoft no longer value older software? Do they presuppose that users no longer want backward compatibility?

    Is it too hard to extend the NT Virtual DOS Machine to the 64-bit architecture? Or is the expectation that I only run the new, 64-bit, XP editions of Microsoft Spiffy from now on?

    Really, I thought Microsoft's big ace was the mountains of old, existing binaries that just worked without needing the source to recompile on their new OSes. Apparently this does not matter any more.
