Why go 64 bit OS? [closed]

On these questions:

  • Which Vista edition is best for a developer machine?
  • Vista or XP for Dev Machine

People are recommending 64 bit, can you explain why? Is it just so you can have more then 3GB of addressable RAM that 32 bit gives you?

And how does Visual Studio benefit from all this extra RAM?

I went from 64 bit XP back to 32 bit due to 90% of the software I was using only being 32 bit anyway and I had issues with drivers and some software with 64 bit.

Why did computers stop at 64-bit?

One of the reasons for migrating from 32-bit to 64-bit computers was memory (RAM) addressing; however, for all practical purposes, there was only a need for a few more bits beyond 32 (see binary values).

What is the main reason to opt for a 64-bit operating system over a 32-bit operating system?

Using 64 bit operating system with 64 bit processer, the system can perform an increased number of calculations per second. As a result, it increases the processing power and makes a computer run faster. This is limited in case of 32 bit operating system.

Why can't 64-bit run 32-bit?

Its because the processor in the case of a 32bit machine cant handle 64bit processing, but a 64bit processor is more than capable of handling 32bits as it can deal with 64bits at a time. Save this answer.

Is 64-bit still used?

64-bit CPUs have been used in supercomputers since the 1970s (Cray-1, 1975) and in reduced instruction set computers (RISC) based workstations and servers since the early 1990s. In 2003, 64-bit CPUs were introduced to the mainstream PC market in the form of x86-64 processors and the PowerPC G5.

Vista, as far as I know, has much better 64 bit support than XP. It is more well advertised than 64 bit XP, and more popular. Driver and software support should be much better for 64-bit Vista.

The 64-bit switch is in progress right now in the computing industry. You might as well switch. Microsoft made the serious leap to 64-bit already, and many have already followed suit. Those who haven't switched, will soon, most likely.

As for the technical benefits, there aren't many aside from the higher memory limits. Vista will certainly allow you to take advantage of the 4GB+ of RAM if you have it on 64-bit though.

A number of reasons.

  1. Yes, you're right it is so you can have more than 3 gig of ram
  2. More and more systems are going to be 64 bit soon so it makes sense to develop on what you're going to be running on
  3. Some bugs can only be observed when running in 64 bit mode
