Win8.1 32-bit and 64-bit difference

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, the following are mainly Great difference.

★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 64-bit CPU GPRs (General-Purpose Registers, general-purpose registers) have 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.

★ Different computer configuration requirements

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

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

We have already introduced the difference between 32-bit and 64-bit systems. So is the computer installed with a 32-bit Win8.1 system or a 64-bit Win8.1 system?

Best The 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 the newly purchased computers are installed with 4GB. 8GB or even larger memory, 32-bit system only supports 3.5GB of memory, which is why it is gradually eliminated. In addition, CPUs now support 64-bit. There is no unsupported problem on the installation, and the 64-bit system speed is relatively high. Faster, so 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.
