The latest computer configuration is stronger than the performance of a few years ago, using XP system is no longer suitable, can not play the full performance of the computer, so win7 system is currently the best select. Win7 and the previous XP system, also divided into several versions, now users generally choose win7 32-bit or 64-bit system, then what is the difference between these two versions of win7 system? Which version of the high use rate is higher?
win7 32-bit and 64-bit difference
First talk about the difference in hardware configuration. A large percentage of netizens who choose 64-bit Windows 7 have a memory greater than or equal to 4GB. In 32-bit Windows 7, it may show that the memory can use 3.25G, which makes many users feel uneasy. That's right, the addressable memory space is really the most notable feature of 32-bit Windows 7 and 64-bit Windows 7.
32-bit CPU (accurately speaking CPU running in 32-bit mode) can only address up to 4GB of memory, subject to this, 32-bit operating system can only recognize up to 4GB of memory, due to In the system, in addition to memory, there are many storage devices, so the real usable memory space is definitely less than 4GB, which is the 3.xxG displayed in the system properties we see.
But the 64-bit CPU has changed a lot. The 64-bit CPU has a maximum addressing space of 2 to 64 bytes. After calculation, its addressable space reaches an astonishing 16TB (treabytes), or 16384GB. Of course, this is only a theory. From the practical application, the versions of Windows 7 64bit are 8GB-192GB respectively. Among them, the Home Edition can support 8GB of memory, the Home Premium can support 16GB of memory, and the 64-bit Windows 7 Professional. The Enterprise and Ultimate versions support up to 192GB of memory.
32-bit Windows 7 configuration
In other words, users with memory greater than or equal to 4GB are limited by 32-bit hardware. Therefore, it is not necessary to maximize the use of hardware resources. The operating system to maximize the use of resources. It should be noted that 64-bit systems require 64-bit CPU support. Please confirm whether your CPU supports 64-bit before installing 64-bit Windows 7. Generally speaking, CPUs purchased after 2006 support 64-bit mode.
If you only consider this point, for users with less than 4GB of memory, 32-bit Windows 7 is more suitable for everyone, because the 64-bit version will take up more system memory resources, and the effect is counterproductive.
Next, let's consider the computing performance, which is also very concerned by many netizens. In theory, the performance on a 64-bit platform far exceeds that of a 32-bit platform. The reason is that the data width of the CPU general-purpose register is 64-bit for the 64-bit platform, and 32-bit for the 32-bit platform. That is, the 64-bit platform can run 64-bit data instructions, and the processor can extract 64-bit data at a time (as long as two One instruction, extracting 8 bytes of data at a time) doubles the 32-bit (requires four instructions, extracting 4 bytes of data at a time), and theoretically the performance is doubled.
win7 32-bit and 64-bit usability
About the good use rate, the average user basically can't feel which version of the system is better, if it is a computer with a memory capacity of 4GB or less, whether it is installed Win7 32-bit system, or win7 64-bit system, will not feel obvious easy to use and not easy to use, if more than 4GB of memory, you should install win7 64-bit system, will not cause a waste of hardware resources. In general, the low-end configuration of the computer, using a 32-bit system is better, the version is lower and simpler, accounting for less CPU resources, which is why the old computer uses XP system to run faster.
