When it comes to purchasing new peripherals and extension cards, two major concerns for computer owners are hardware and software compatibility. Terms like "64-bit" can be confusing and may cause confusion among buyers. You can confirm that the graphics card you want to buy will be compatible with your hardware and operating system by following a few recommendations.
Modern operating systems exist in two distinct editions, a 32-bit version and a 64-bit one. The number of bits expressed relates to the amount of numerical data that a central processing unit can process simultaneously. Therefore, the compatibility between an operating system and a computer is determined by the machine's CPU. If a computer contains a 64-bit CPU, that machine will be able to run both the 64 and the 32-bit versions of an operating system. On the other hand, a 32-bit CPU can only run a 32-bit operating system.
A number of bits is typically affixed to the full name of a graphics card. However, as opposed to CPU's, the number of bits that a graphics card can handle does not express the amount of data that a CPU can process. Instead, that number refers to the maximum amount of data that can be transferred between the card's random-access memory and the graphics processing unit. The more bits a graphics card has, the faster data can be stored or retrieved from the RAM.
Because the number of bits used by operating systems and graphics cards does not relate to the same function, that number does not impact compatibility. A customer can then install a 64-bit graphics card, for example, on a 32-bit operating system. You should, however, be careful about any other potential hardware incompatibility, such as the type of slot used by the card and the slots available on your motherboard.
GPU manufacturers typically release drivers for graphics cards in two separate versions, 32 and 64-bit. Drivers are software packages that help your computer communicate with the graphics card. Since the number of bits used in the description of drivers refers to operating system bits, it is important to download the same version as your operating system's. For example, if you have a 32-bit operating system, you should only download the 32-bit version of your graphics card's drivers.
