is the 64-bit Win7 system really faster than the 32-bit Win7?

Windows 7 has 32-bit versions and 64-bit versions, but must 64 be faster than 32-bit?

First of all, I believe that the choice of 64-bit Windows 7 users in a large proportion of the storage body is greater than or equal to 4GB. If you have 32-bit Win7, the memory that you can use appears to be 3.25G only. So where are the rest of the rest of the memory? Please continue to look down.

CPU in 32-bit mode, can only be addressed to the largest 4GB of storage, subject to this, the 32-bit operating system can only recognize the largest 4GB of storage, because in the system, in addition to memory, there are other storage devices, so the real memory can be used for storage space less than 4GB, Which is the 3.25GB that we see in the system properties.

However, the CPU in 64-bit mode is different, the maximum addressable space of 64-bit CPU is 2 of 64 Times Square bytes, its addressable space reaches an astonishing 16TB (treabytes), that is 16384GB. Of course, this is just a theory, in fact, the 64-bit WINDOWS7 versions are 8GB-192GB, where:

1, the Home normal version of the highest support 8GB storage body.

2, home advanced version of the highest support 16GB storage body.

3, Professional Edition, Enterprise Edition and flagship edition can support 192GB storage.

For a user with a storage body greater than 4GB, you can choose to install a 64-bit operating system because it is limited by the 32-bit operating mode and cannot maximize the use of hardware resources. Note, however, that 64-bit operating systems require the support of the CPU 64 mode, that is, its instruction set contains EM64T. Before installing 64-bit Win 7, make sure your CPU supports 64-bit mode, and in general, the CPU purchased after 2006 years supports 64-bit mode. (with Cpu-z This small software can see whether your CPU supports 64-bit mode, view method and cpu-z download address I will attach to the end of the article.) )

32-bit Win7 is more appropriate for users who are less than 4GB in storage because 64-bit Win7 consumes more system storage resources.

Secondly, we can compare the performance of the operation. In theory, the performance of the 64-bit platform is far more than 32-bit platform, because the CPU general register of the data bit width is different, 64-bit platform is 64 bits, 32-bit platform is 32-bit. The 64-bit platform can run 64-bit instructions, the processor can extract 64-bit data (8 byte data at a time), one more than the 32-bit (4-byte data at a time), and in theory, performance will increase by 1 time times.

However, although the operating system is 64-bit, it requires 64-bit application software to play the advantage of 64-bit operating systems. Running 32-bit applications under 64-bit operating systems will not improve performance, and only 64-bit applications can play the advantage of a 64-bit platform. For now, 64-bit applications are well below 32-bit operating systems in both kind and quantity, but more and more software developers are porting their software to 64-bit platforms. At present, there are still many software incompatible with the Windows 7 64-bit version, I believe that over time, more and more software can be applied to the 64-bit platform.
