32-bit and 64-bit system which is good?

The difference between 32-bit systems and 64-bit systems has the following four points:

First, the CPU requirements are different

CPU has 32-bit and 64-bit, 32-bit CPU can only install 32-bit system, while 64-bit CPU can install 32-bit system can also install 64-bit system

Second, the operation speed is different

The 64-bit CPU instruction set can run 64-bit data instructions, up to one more than 32-bit CPUs (theoretical value, 64-bit software support required)

Third, the addressing ability is different

64-bit systems can support up to 128 GB of memory and up to terabytes of virtual memory, while 32-bit CPUs and operating systems can support only 4G of memory (actually 3G or so).

Four, software compatibility is different

At present, 64-bit system compatibility is already very good, most of the software has been supported 64 bits, or even some software only to launch 64-bit version, such as premiere, and 64-bit software in the 32-bit system can not run. But in contrast, 64-bit compatibility is really not as good as 32-bit systems.

So, for now, the difference between Windows 32-bit and 64-bit systems is mainly two

1, 64-bit system can support more than 4G of memory

2, 64-bit compatibility less than 32-bit systems (less compatible)

However, as software compatibility becomes more and more good, 64-bit software more and more, 64-bit system advantages will gradually play out, 32-bit system is replaced only a time problem!
