The difference between win10 32-bit and 62-bit

The difference between win10 32-bit and 62-bit

What is the difference between Win10 32-bit and 64-bit, today The differences between the two are sorted out.

1. Different original design intentions

The original design intention of the 64-bit operating system is to meet the needs of mechanical design and analysis, three-dimensional animation, video editing and creation, as well as scientific computing and Customer demand in areas such as high-performance computing applications that require large amounts of memory and floating-point performance.

2. Different configuration requirements

64-bit operating system can only be installed on a 64-bit computer (the CPU must be 64-bit). At the same time, you need to install 64-bit common software to get the best performance of 64-bit (x64). 32-bit operating systems can be installed on 32-bit (32-bit CPU) or 64-bit (64-bit CPU) computers. Of course, when a 32-bit operating system is installed on a 64-bit computer, its hardware is like a "big horse-drawn cart": 64-bit performance will be greatly reduced.

3. Different operating speeds

The data width of 64-bit CPU GPRs (General-Purpose Registers, general-purpose registers) is 64 bits, and the 64-bit instruction set can run 64 bit data instructions, which means that the processor can extract 64-bit data at a time (only two instructions are required to extract 8 bytes of data at a time), which is higher than 32-bit (requiring four instructions to extract 4 bytes of data at a time) If it is doubled, theoretically the performance will be doubled accordingly.

4. Different addressing capabilities

The advantage of 64-bit processors is also reflected in the system's control of memory. Since addresses use special integers, an ALU (arithmetic logic unit) and registers can handle larger integers, which means larger addresses. For example, Windows Vista x64 Edition supports up to 128 GB of memory and up to 16 TB of virtual memory, while 32-bit CPUs and operating systems can only support up to 4G of memory.

5. Software popularity is different

Currently, 64-bit commonly used software is much less common than 32-bit commonly used software. The reason is simple: relatively few users use 64-bit operating systems. Therefore, software developers must consider the "input-output ratio" and invest limited funds into software for more user groups. This is also an important reason why 64-bit software is relatively expensive (spreading the cost over fewer releases).

It is particularly emphasized here that 64-bit computers can install 32-bit operating systems, but 32-bit computers must not install 64-bit operating systems. This is important to remember to avoid blind downloads and installations.

If you don’t know whether your computer’s CPU is 64-bit, you can check it through some software. For example, you can use CPU-Z to complete the detection.
