Win8.1 32-bit and 64-bit difference 32-bit and 64 which is better?

We know that starting from Win7, Windows systems are divided into 32-bit and 64-bit versions. Regarding 32-bit and 64-bit, it is also a hot topic for computer enthusiasts. Many friends today install Win8.1 system. If you install the system yourself, you can also see the 32-bit and 64-bit versions when you download the Win8.1 system image. The question is, the difference between Win8.1 32-bit and 64-bit, which is better? The following small series and everyone analyze together.

The difference between 32-bit and 64-bit in Win8.1 system is actually the difference between 32-bit system and 64-bit system. In summary, there are mainly the following differences.

★The original design is different

The 64-bit operating system was originally designed to meet mechanical design and analysis, 3D animation, video editing and creation, and scientific computing and high performance computing applications. The customer needs a lot of memory and floating point performance, and the 32-bit system did not consider too much in the early days.

★Different operation speed

Installing a 64-bit system requires the CPU to support 64-bit, while the 64-bit CPU GPRs (General-Purpose Registers) has a data width of 64 bits and 64 bits. The instruction set can run 64-bit data instructions, which means that the processor can extract 64-bit data at a time (as long as two instructions, extracting 8 bytes of data at a time), than 32 bits (requires four instructions, extracting 4 words at a time) The data of the section has been doubled, and the theoretical performance will be doubled accordingly.

★The memory addressability is different

32-bit system, the maximum can only support 3.5GB memory, if you use 4GB or more memory in 32-bit system, the computer can only It recognizes that 3.4GB is available, while a 64-bit system can support up to 128GB of memory.

★The computer configuration requirements are different

The 64-bit operating system can only be installed on a 64-bit computer (the CPU must be 64-bit), and the computer hardware requirements are relatively high. Install 64-bit software to get the best performance from 64-bit (x64).

Win8.1 32-bit and 64 which is better?

The above we have introduced the difference between 32-bit and 64-bit systems, so is the computer installed 32-bit Win8.1 system or 64-bit Win8.1 system?

The best answer is: 64-bit Win8.1 system

The reason is that today's 64-bit systems are very mature, most of the software has been optimized for 64-bit systems, and now new purchases The computer is installed with 4GB, 8GB or even more memory. The 32-bit system only supports 3.5GB of memory. This is why it is gradually being eliminated. In addition, the CPU now supports 64-bit. There is no unsupported installation. The problem, combined with the relatively fast 64-bit system, is the preferred 64-bit Win8.1 system.

For some classic computers with low configuration and less than 4GB of memory, it is recommended to install a 32-bit system.
