Windows 7 is here, promised to be a whole lot more stable than Windows Vista, Microsoft is anticipating Windows 7 to be a runaway success when it is launched this coming August or September. One of the main feature of Windows 7 is its 64-bit operating system technology, not that previous OS doesn’t support 64-bit, perhaps it is time the much awaited transaction gain the required momentum.

Microsoft Windows 7 And Vista - 64 bit vs 32 bit Pro And Con

The benefit from using a 64-bit computer

The benefits of using a 64-bit processor and operating system is the ability to amount large random access memory (RAM). A typical operating system and processor with 32bit technology can only handle 4GB of RAM, however, a 64-bit operating system and processor a larger allocation, which in turn allows a much more responsive computing experience.

64-bit version of Windows, drivers, hardware and software required

To truly experience the 64-bit experience, you’ll need a 64-bit driver, operating system, hardware, and software. Now, imagine a highway with 64 lanes and once it reaches the city it is narrowed down to 32 lane, this would create a bottleneck, thus reducing the traffic flow. Same goes with computers, everything must be compatible or else it doesn’t make any sense to switch over.

Summary of Pro and Con of 64-bit Processor

  • 16 bit application will not work anymore.
  • Existing 32 bit drivers does not work on a 64 bit operating system.
  • Unsigned kernel-mode drivers no longer work.
  • Very little x64 software currently exists.
  • Vista and Windows 7 x64 currently does not backward support most x86 (32-bit) drivers.
  • Running some 32 bit applications on a 64 bit OS could actually be slower.
