Detailed explanation of the difference between 64-bit and 32-bit win7 system

Many netizens know that win7 system has 64-bit and 32-bit distinctions, but few people know the difference between 64-bit and 32-bit win7 systems. Some netizens said that they have used both systems and feel that there is no difference. . The editor below will introduce to you the differences between 64-bit and 32-bit win7 systems.

1. Resource Utilization

Win7 32-bit system, 32-bit occupies less memory, but does not support memory larger than 4G. In other words, installing 32-bit system memory larger than 4G memory is a waste. Cannot be used effectively.

win7 64-bit system, 64-bit system supports up to 128G memory. If your memory is relatively large, install 64-bit to maximize the use of resources.

2. Computational performance

The running performance on the 64-bit platform is far higher than that on the 32-bit platform. The reason is that the data bit width of the CPU general register is 64 bits on the 64-bit platform and 32 bits on the 32-bit platform. In other words, the 64-bit platform can run 64-bit data instructions, and the processor can extract 64-bit data at a time (as long as two instruction, fetching 8 bytes of data at a time), which is doubled compared to 32-bit (requiring four instructions, fetching 4 bytes of data at a time), and theoretically the performance will be doubled accordingly.

3. In terms of use

Ordinary users basically cannot feel which version of the system is better to use. If it is a computer with a memory capacity of less than 4GB, no matter Whether you install win7 32-bit system or 64-bit system, you will not feel the obvious ease or difficulty of use. If the memory is greater than 4GB, you should install win7 64-bit system, which will not cause a waste of hardware resources. Generally speaking, for computers with mid-to-low-end configurations, it is better to use 32-bit systems, which are lower and simpler versions and occupy less CPU resources. This is why older computers run faster using XP systems.

4. Support different processors

32-bit operating system can only support 32-bit processors, while 64-bit operating system can support 32-bit processors at the same time processors and 64-bit processors.

5. Different supporting software

32-bit operating system only supports 32-bit software, while 64-bit operating system can support both 32-bit software and 64-bit software. bit software.

The above is the difference between 64-bit and 32-bit win7 system. I hope it can deepen everyone's understanding of win7 system.
