Explain me about x64 systems?

By naylynnaung ·
My computer uses Wolfdale processor runs at 2.60 GHz. Level 2 Cache 2 MB. FSB 800 MHz. I know that this processor supports 64 Bit Architecture. I want to use 64 Bit system such as Windows XP 64 Bit Edition, Windows 7 64 Bit Edition. But some of my friends told me that if I want to use 64 Bit system, I must install the 64 Bit version of both OS and Application Software in order to get benefits from 64 bit Architecture. Can I use 32 Bit Applications in 64 Bit OS? For example, 64 Bit Version of Windows 7 with 32 Bit version of Microsoft Office 2007 Enterprise Edition.

Let me try to be clear.

Yes, I've understood the difference between 32 bit and 64 bit (and 16 bit) for a long time.

My point, and I do have one, is that there is more to the application, especially games. If the Direct X, being part of the 64 bit OS, is 64 Bit, and it handles calls to the video, audio, networking hardware, then the game will run somewhat faster than it would on a system where Direct X is running in 32 bit. Same with the .Net framework, video drivers etc.

Or are you tell me that when you launch a 32 bit app on a 64 bit OS system, that the whole thing,Direct X, drivers included, runs ina 32 bit compatability mode?

the processor will only process in 32 bit word

by CG IT In reply to Let me try to be clear.

Deleted the overly long post.

Yes, the whole thing runs 32 bit word per cycle because the application and it's APIs are 32 bit word.
