Only a few years ago, 32-bit vs. 64-bit was something that only people using Linux had to concern themselves with, but that has quickly changed. Now almost every computer or laptop has both 64-bit and 32-bit options. You might be preparing to purchase a new computer or do an upgrade to an existing system and wondering, “Which version should I choose?” or “Does it really matter and why?”.
The amount of data a chip can process at once is the main difference between 32-bit and 64-bit processors. The 64-bit CPUs can handle more memory and larger files. However, even if your computer has a 64-bit processor, it will not be able to benefit from it unless it also has a 64-bit operating system.
The primary benefit of moving to a 64-bit system is improved performance. The performance benefit is related to two factors: the ability to use more RAM and amount of data that can be moved around is increased. 32-bit operating systems are typically limited to using 4 gigs of RAM, even if more is installed on the computer. This means that processing power has an upper limit. In contrast, 64-bit systems can access over 16 billion gigabytes of memory – much more than your computer can likely accommodate. This means that a 64-bit system can use much more memory and ultimately perform faster.
Keep in mind that only applications that are optimized for 64-bit will run faster than their 32-bit equivalents. Also, unless you are performing very memory intense tasks like video editing or complex mathematical calculations you probably won’t notice a huge performance difference between a 64-bit and 32-bit system with the same amount of RAM.
There are a few considerations for moving to a 64-bit system. The first possible issue associated with 64-bit operating systems – one that might eliminate the option entirely – is does your CPU support 64-bit. The processor in your computer must have 64-bit support. Although the majority of computers today support 64-bit software, older or lower-end, less expensive budget devices may not.
Another possible challenge of moving to a 64-bit operating system is that some hardware drivers or other software programs may not be available in 64-bit versions. Although most 32-bit applications will function properly on a 64-bit operating system, some like low-level device drivers and anti-virus applications may not.
You should also be aware that more disk space is typically required to install a 64-bit operating system than the 32-bit version. However, this isn’t an issue on most modern computers given the extremely large hard drives.
