64-bit computing is replacing 32-bit, mainly because 64-bit enables faster hardware and software. Here's the rundown on the ongoing 32-bit vs. 64-bit debate. Skip to main content ...

Installing a 32-bit OS on a 64-bit-architecture system can work, but it's not optimal. A 32-bit OS, for example, has more limitations—the standout being it can only really utilize 4GB of RAM.

While a 64-bit processor can run a 32-bit operating system, the reverse is not true. If your computer has a 32-bit processor, the decision has already been made for you.

More and more frequently, users are installing the 64-bit version of their operating system of choice over the less capable 32-bit version. But most people don't really have a full understanding ...

The terms 32-bit and 64-bit refer to the way a computer’s processor or CPU, handles information. The 64-bit version of Windows 11/10/8/7 handles large amounts of random access memory or RAM ...

X64 is the 64 bit extension technology that AMD invented (AMD64) to seamlessly migrate the 32 bit x86 (as in 286, 386, 486 compatible microprocessors) world into a 64 bit era.

The difference between Windows 32-bit and 64-bit is processing power. A 64-bit processor can handle more data simultaneously, so it's more capable overall. Most new processors are based on the 64-bit ...

If you run a 32 bit OS on a 64 bit machine with 4GB ram or less you still save a lot. You can even run it with more RAM (using the address extensions features of x86) and you save a lot.

My benchmarking marathon last week seemed to generate more questions and requests for further benchmarking. A popular request from you, Constant Reader, was to see Windows Vista 32-bit benchmarked ...

For example, on Windows Vista 64-bit, 32-bit applications must be “thunked” via the WoW64 (Windows on Windows) subsystem to run. Similar methods are used in other operating systems.
