Many also doesn’t know what is the difference between those two version. Well, as per my experience, below is the difference that I can see.
1) Minimum requirement for Hardware
Before installing Windows 7, u must know which version that u want to run with either 32bit or 64bit. If u have an old CPU such as Pentium 3 or lower & 512MB of RAM or lower, then u should just stick with windows XP. Why? Becoz ur hardware will surely cannot support windows 7. But, if u have the latest CPU & more than 1gb of RAM, then it shouldn’t be an issue running 32bit or 64bit. Just need to decide between each version.
2) RAM / Memory utilization
The obvious difference is the maximum amount of RAM that will be utilized by windows. If u are running a 32bit windows, the maximum amount is 3gb. Microsoft has announce this in their support website. (Click here to read article). As for the 64bit, windows can fully utilized the amount of RAM and this is ideal for gamers, multi-tasker, graphic designer, etc.
3) Type of software used / can run on 64 bit
Many would think that having a 64bit Windows will make application run faster. That is half true. Worst of all, 32bit application will run much slower on 64bit Windows. Currently not all applications is written & optimized for 64bit processing speed. Today’s software is still designed for 32bit era. Maybe in another 1 or 2 years, software will be written & optimized for 64bit 🙂 (maybe)
4) Device drivers
64bit Windows are using different device drivers and surely will not work with 32bit device drivers. Unfortunately, most drivers nowadays is for the 32bit. Currently most hardware company are updating their drivers database. Hopefully drivers problem can be resolve within this year 😉
Hope this little info could help 🙂
