Win7 system 32 and 62 bit difference how much do you know

  
Windows 7 SP1 Chinese Ultimate is an operating system developed by Microsoft Corporation. The system home is available for downloading the official Win7 system. Windows 7 is available for home and business work environments, laptops, tablets, multimedia centers, and more.

Next, follow the system home Xiaobian to learn about the difference between the 32-bit version of the Windows7 system and the 64-bit version:
The first point, the original design is different
64-bit operating system Originally designed to meet the needs of customers who require large amounts of memory and floating point performance in areas such as mechanical design and analysis, 3D animation, video editing and authoring, and scientific computing and high performance computing applications.
The second point, the requirement to configure different
64-bit operating system can only be installed on a 64-bit computer (the CPU must be 64-bit). At the same time, 64-bit commonly used software needs to be installed to achieve the best performance of 64-bit (x64). The 32-bit operating system can be installed on a 32-bit (32-bit CPU) or 64-bit (64-bit CPU) computer. Of course, the 32-bit operating system is installed on a 64-bit computer, and its hardware is just like "big horse car" ": 64-bit performance will be greatly reduced.
The third point, the operation speed is different
64-bit CPU GPRs (General-Purpose Registers, general-purpose registers) data width is 64 bits, 64-bit instruction set can run 64-bit data instructions, that is, the processor once Can extract 64-bit data (as long as two instructions, extract 8 bytes of data at a time), double the 32-bit (requires four instructions, extract 4 bytes of data at a time), theoretically the performance will be improved accordingly 1 times
Fourth point, different addressing capabilities
The advantages of 64-bit processors are also reflected in the system's control of memory. Since the address uses a special integer, an ALU (Arithmetic Logic Operator) and registers can handle larger integers, which are 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 4 GB of memory.
The fifth point, the popularity of software is different
At present, 64-bit commonly used software is much less than 32-bit commonly used software. The reason is simple: there are relatively few users using a 64-bit operating system. Therefore, software developers must consider the “input-output ratio” to invest limited funds into the software of more users. This is also an important reason why 64-bit software is relatively expensive (to spread costs into fewer offerings).
It is especially emphasized here that although a 64-bit computer can be installed with a 32-bit operating system, a 32-bit computer must not be installed with a 64-bit operating system. This is important to keep in mind to avoid blind downloads and installations.
