Windows system 32-bit and 64-bit differences

Memory support: 32-bit Windows system can only run or process up to 4GB of memory, when the computer installed more than 4GB, the system will not recognize more than 4GB of memory. Also said is installed >=4GB above memory, installed and not installed is the same.

While the 64-bit system may support more than 4GB of memory, less than 128GB of memory (WIN7 64-bit), but if it is purely from the CPU, the maximum addressable 16TB of memory. However, home computers or office computers, generally limited by the computer motherboard, generally support up to 16 or 32GB of memory, this very large memory, more than the server.

Computer Repair Technology Network Note: Many online users have found some XP 32-bit system, made a crack patch, can support 4GB or large memory, the author here This need to explain, how much do you want? Can I help you change to 100G of memory? Do you think it's useful? The problem is that the computer simply doesn't have the big memory.

Application software: Running 32-bit software applications in 64-bit systems does not allow users to experience a leap in performance and feel the same. In previous years many games did not support 64-bit systems, there are 64 of games can not be entertained, but now many game manufacturers have begun to migrate from 32-bit system to 64-bit system platform, but there are some games or software does not support the 64-bit platform system, but believe that time will solve the problem.

Computing speed: Theoretically 64-bit platform system will exceed the 32-bit platform system, the main reason is the CPU universal register data bit width, 64-bit platform can process and run 64-bit data instructions, the CPU can extract 64 bits of data at a time, the theoretical performance of the 32-bit system increased by one times.
