A few years ago we had orginally planned to support the IA64 infrastructure, but now I think we've dropped the support plans. Anyone here actually use an IA64 machine? If so, how does it compare to amd64 machines?

 

I've used both and I find AMD64 to be superior in almost every respect.

I have a Windows 64 bit system and it FLIES with the AMD.

 

What kind of benchmarked comparisons have you made?

 

Well considering that they really are apples to oranges, I've only compared them in terms of price and application/OS speed.

I'd be interested in a real benchmark but I'm not sure if thats possible considering they run on incompatible instruction sets.

 

Sure, a C++ app can be compiled for either processor and link to the same API calls.

Why are you running XP64?

My thoughts on it...

Really no advanatge right now. 32bit apps get slowed down by the wow32 translator. Current 64bit apps provide 3-16% speed increase, but there is few to none out yet.

Then there's few and far between drivers for XP64... (I like to have the latest drivers usually)

No-one has written a AMD64 excluse app to really make the processor shine...

The #1 advatage of 64bit processor is how much memory the application can address and my 32 bit apps can currently allocate 4GB, I only have 2GB of ram on this box...

I don't plan on moving over to XP64 until the end of this year, if even then... I do have it setup so I boot into it. However I rarely use it.

Kinda curious as to what your doing with it.... I didn't find much need/use for it *yet*

 

sweet what did you use the IA64 for? some ppl at work had a hard time getting much of anything to run on it

 

Some military apps are 64 bit and are being beta tested

In my case, its for sonar work. Pretty complicated stuff.

 

sweet

did you have any issues with compatibality? also did the apps start as 32 bit and scaled to 64, or were they built solely for 64 bit?

its ok, i have secret clearance, you can tell me

 

They are solely built for Windows 64 bit

As far as I know, they are one of the very very few true 64 bit windows apps out there.

 

Speaking of Windows 64 bit, I just got the release candidate in the mail today. Installing it in a minute
