The difference between system 32 and 64 of windows 7 pro
1. The difference of design original
The original design of 64 bit operating system is:meetting the mechanical design and analysis, 3D animation, video editing and creation, require a lot of memory and floating point performance and scientific computing and high performance computing applications in the field of customer demand. In other words, they are the platform for the use of special software in the industry. The 32 bit operating system is designed for the average user.
2.The difference of addressing capability
The advantage of the 64 bit processor is also reflected in the control of the system to the memory. Because it's a special integer of address used, a ALU (arithmetic logic unit) and the register can handle a larger integer, which is a larger address. For example, Vista x64 Edition Windows supports up to 128 GB of memory and up to 16 TB of virtual memory, while the 32 bit CPU and operating systems can only support 4G memory.
3.Different configuration requirements
64 bit operating systems can only be installed on 64 computers (CPU must be 64 bits). At the same time need to install 64 commonly used software to play the best performance of 64 (x64). 32 bit operating system can be installed in 32 (32 bit CPU) or 64 (64 bit CPU) on the computer. Of course, a 32 bit operating system installed on a 64 bit computer, the hardware is the "big horse drive the little car": 64 efficiency will be greatly reduced.
4.The different of Speed operation
It is a long story to say the 32 bit and 64 bit system, here we first look at the CPU architecture technology, usually we can see in the computer hardware will have X86 and X64 logo, this is actually two of different hardware architecture of CPU , X86 stands for 32 bit operating systems, x64 stands for 64 bit operating systems. Then what's the meaning of "bit" in 32 and 64? Compared with the 32 bit technology, 64 bit technology this figure refers to the CPU (GPRs General-Purpose Registers, a general register) data width is 64 bits, 64 bit instruction set is running a 64 bit data command, that is to say you can run a 64bit data processor. For example, it is easy to understand but not particularly accurate: the 32 bit throughput is 1M, while the 64 bit throughput is 2M. So the performance of the 64 systems is 1 times higher than that of the 32.
5.Different software popularization
At present, 64 commonly used software is much less than 32 commonly used software. The reason is very simple: the users who use 64 bit operating system are relatively small. As a result, software developers must consider the "input output ratio", put the limited funds into more use of the group's software. This is the reason why the price of the 64 software is relatively expensive.
