As we know, when start from window Window XP, every window have 32bit and 64 bit,

but most of the people still don't know what's the different between them.

Here are some compare with Window 7 32bit and 64bit:

1.RAM Support

The main different between 32bit window & 64bit window is the memory that can be utilised



Although 32bit window can support 4gb ram, but the system will remain some of them for



system use, so in reality , there are only about 3.25gb can be use in 32bit window.

But 64bit can fully use the ram up to 128gb.

32bit=0 64bit=1

2.PcMark Vantage performance test

PcMark Vantage is a application which can test the performance of the system across a variety

of common tasks such as viewing and editing photos, video, music and other media, gaming,

communications, productivity and security.




As we can see 64bit is more high score then 32bit in Memery,Gaming,Communication, and

Productivity. But in Tv & Movies,Music and HDD test, 32bit perform as well as 64bit.

However, the result show 64bit perform better then 32bit about 13%.

32bit=0 64bit=2

3. 7-zip/Winrar

When come to compressing files, two software had been used for testing-WinRAR & 7-Zip.



▲From the graph we can see that 64bit can perform faster when using 7-zip,
but no much different with WinRAR.

▲We can see that 64bit just need 198second and 157second to compress a 433MB file when using7-zip and WinRAR.

32bit=0 64bit=3

4.Convert video & music

At video converting , the test used Windows MediaEncoder to convert a MPEG video into WMV format.
For audio, iTunes had been used for convert WAV into MP3 format.

▲As we can see,64bit used 271 second to convert a video file which faster then 32bit for 7 second. But when comes to audio convert, both of them used same time to convert.

32bit=0 64bit=4

5.Compatible

When come to compatible, although 64bit also support 32bit application, but 64bit window can't use 32bit driver or antivirus. To 100% perform well in 64bit window, not only RAM, but also need the application also have a version of 64bit, if using a 32bit application on 64bit window, it still cant perform the best performance in 64bit window.



32bit=1 64bit=4

CONCLUSION:

32bit=1 64bit=4
However, although these test show that 64bit window perform better than 32bit,
but the test are using the application which have 64bit version to test in 64bit window.
If the user using 32bit application, then the performance will be different.

So, before thinking of using 32bit or 64bit window, you have to consider does the driver of your computer and the application that you often use support 64bit window.
