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

Windows 7 has a 32-bit version and a 64-bit version, but is 64-bit faster than 32-bit?
First of all, I believe that a large percentage of netizens who choose 64-bit Windows 7 are those with a storage volume greater than or equal to 4GB. If you are using 32-bit Win7, the available memory is displayed as only 3.25G. So where did the rest of the memory go? please watch the following part.
The CPU in 32-bit mode can only address a maximum of 4GB of memory. Due to this, the 32-bit operating system can only recognize up to 4GB of memory, because in the system, in addition to memory. There are other storage devices, so the memory space that can really be used for memory is less than 4GB, which is 3.25GB shown in the system properties we see.
But the CPU in 64-bit mode is different. The maximum address space of the 64-bit CPU is 2 64-byte bytes. After calculation, the addressable space reaches an astonishing 16TB (treabytes), which is 16384GB. Of course, this is just a theory. In fact, each version of 64-bit Windows 7 is 8GB-192GB, of which:
1, the home regular version supports up to 8GB of storage.
2, Home Premium Edition supports up to 16GB memory.
3, Professional, Enterprise and Ultimate can support up to 192GB of storage.
For users with a storage volume greater than or equal to 4GB, due to the limitation of the 32-bit operating mode, hardware resources cannot be maximized. At this time, you can choose to install a 64-bit operating system. Note, however, that a 64-bit operating system requires the CPU to support 64 mode, ie its instruction set contains EM64T. Before installing 64-bit Win 7, please make sure that your CPU supports 64-bit mode. Generally speaking, CPUs purchased after 2006 support 64-bit mode. (With CPU-Z this small software you can check whether your CPU supports 64-bit mode, view method and CPU-Z download address I will attach at the end of the article.)
For users with less than 4GB bank, 32-bit Win7 More suitable, because 64-bit Win7 will take up more system memory resources.
Secondly, we will compare the performance of the computing. In theory, the performance on a 64-bit platform is much higher than that of a 32-bit platform, because the data bit width of the CPU general-purpose registers is different, the 64-bit platform is 64-bit, and the 32-bit platform is 32-bit. 64-bit platform can run 64-bit instructions, the processor can extract 64-bit data at a time (8 bytes of data at a time), double the 32-bit (4 bytes of data at a time), in theory, performance Will increase by 1 time.
However, although the operating system is 64-bit, it requires the application software to be 64-bit to take advantage of the 64-bit operating system. Running a 32-bit application under a 64-bit operating system does not improve performance. Only 64-bit applications can take advantage of the 64-bit platform. For now, 64-bit applications are much lower in type and number than 32-bit operating systems, but more and more software developers are beginning to port their software to 64-bit platforms. Currently, there are still many softwares that are not compatible with the 64-bit version of Windows 7, and it is believed that more and more software will be available on 64-bit platforms over time.
