Does a dual Xeon process data like an AMD 64 bit processor?

[videocheez]

I'm investing a lot of money in a dual Xeon computer while reading a little bit about the new 64bit Windows OS and was wondering will the dual Xeon computer be able to take full advantage of the new OS.
I know this may be oversimplified but I was thinking that the 2 x 32 bit processors can be configred to act like one 64 bit processor?
Perhaps I'll need to get a new comp once the new OS is availble but for as much money as I'm spending now, I'm gonna have to live with this baby for at least 4 to 5 years.

Thanks in advance,

VC

Nope. Sorry. Two or four 32-bit CPUs is still a 32-bit machine

I wouldn't worry about 64 bit apps since there isn't too many of them out there.

Dual xeons is way faster than a single P4 though

Dual xeons is way faster than a single P4 though

When running a single app at the same rated GHz chip
Xeons are almost identical in speed to the equivalent P4's. In some
tests they actually rate slightly slower. Where the Xeon blasts the P4 is when
multiple multi threaded applications are run at the same time. Even
then the net increase in speed is less than two equivalent P4's running
in separate boxes. Keep in mind I am talking about overall speed. Specific
aplications designed for Xeon's special features will, of course, run faster - eg. Procoder which takes advantage of the larger L1 cache and
longer pipeline.

Also AFAIK unless omething changed XP64 is still not avaible.

It's not available for standalone purchase but it is out there. You'd have to buy a system preconfigured with it.

no -- the true new winxp 64 bit os is not "out there" (except as beta) , there IS a win 64 os out there for the now pretty well defunct itainium intel chips...

you can confirm this just about anywhere ..

the latest xeons can do 64 bit apps also -- both they and the 64 bit amd are very good ... but as mentioned -- hardly ANY 64 bit apps and drivers are still scarce or in beta or not available.

Dude, you're getting CPUs for that rig with 64-bit instructions. There are folks running 64-bit Linux distros on dual Noconas that are just as fast and stable as similar Opteron platforms. However the Opteron on a 64-bit platform will still outperform the Intel platform as they do a lot better when number-crunching. I think the Intel platforms are still winning the multimedia war so far.
