How can you tell if a 32 bit app will run on an AMD 64 x2 computer before you try it?

I'm considering buying an AMD 64 bit x 2 Turion notebook computer, but don't know if my existing 16 and 32 bit apps will work on it. Also how do I tell if an app I'm thinking of buying will run on it , if it doesn't say so on the packaging such as an older game, etc.?


Thanks.|||Most possibly, it will run well in AMD 64.





AMD's 64-bit processor uses an extended 32-bit instruction set (AMD64, aka x86-64), unlike some Intel's 64-bit which uses a completely new instruction set (IA-64), which makes many older programs run in compatibility layer (legacy mode), resulting in loss of performance when running 32-bit apps in it and less compatibility. With AMD's the 32 bit program runs in 64-bit environment natively, making performance loss negligible and compatibility wider, although since the programs are designed for 32-bit they won't be capable of accessing the extra features.





The problem, however, if it exist, would be with the Operating System (OS). If you used a 64-bit OS, there might be incompatibilities introduced by the OS (although it's quite rare). If you used 32-bit OS in 64-bit processor, all would be perfectly fine.|||Your apps will run fine. Remember, not many applications take advantage of a 64-bit architecture (mostly server programs). I wouldn't worry.|||if its base under x86 (x32) it works just fine! on x64





GOD!!
