Microsoft since the win7 system, it is divided into 64-bit and 86-bit (ie 32-bit), many users in the upgrade win10 system when they want to choose the operating system, choose 32-bit Or 64-bit, in fact, for users, 32-bit or 64-bit difference is not very big, the choice of operating system is determined by the user's hardware configuration, the following small series for everyone to introduce their home the difference.
The difference between Win10 32-bit system and 64-bit system:
1, different design intentions
64-bit operating system is designed to meet mechanical design and analysis, 3D animation, video editing and creation And the need for large amounts of memory and floating point performance in areas such as scientific computing and high-performance computing applications, while 32-bit systems have not been considered too much in the early days.
2. Different computing speeds
Installing 64-bit systems requires 64-bit CPU support, while 64-bit CPU GPRs (General-Purpose Registers) have a data width of 64 bits and a 64-bit instruction set can run 64. Bit data instruction, that is to say, the processor can extract 64-bit data at a time (as long as two instructions extract 8 bytes of data at a time), which is higher than 32 bits (requires four instructions and extracts 4 bytes of data at a time) Doubled, theoretically the performance will be doubled accordingly.
3, memory addressability is different
32-bit system, the maximum can only support 3.5GB of memory, if in the 32-bit system, using 4GB or more memory, the computer can only recognize 3.4GB available The 64-bit system can support up to 128GB of memory.
4, different computer configuration requirements
32-bit system has lower configuration requirements, 64-bit, non-64-bit CPU support 32-bit system, but wasted 64-bit CPU and can only recognize 3.2 G memory;
64-bit system has high configuration requirements, and the CPU has to be 64-bit; but 64-bit system addressing capacity is twice that of 32-bit systems, that is, task processing capability is faster than 32-bit. Times, can recognize more than 128G memory; but 64-bit system has a problem, and quite a lot of software is not compatible! Especially the driver, must distinguish between 32-bit and 64-bit; and 64-bit system is not compatible with some software and games, run No; the system structure is different from 32-bit, it is more troublesome to manage!
Win10 32-bit and 64 which is better?
The above we have introduced the difference between Win32 system 32-bit and 64-bit, then the computer is installed 32-bit Is the system good enough to install a 64-bit system?
The answer to the small series is: 64-bit Win10 system
The reason is that 64-bit systems are now very mature, and most software has been optimized for 64-bit systems, and Newly purchased computers are now installed with 4GB, 8GB or even larger capacity. Save, 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 in installation, and 64-bit system is relatively faster, so 64 is preferred. Bit Win10 system.
Through the above small series introduction, I think everyone has chosen what kind of operating system has been in mind.
