One of the fundamental pieces that make up your computer is the processor. It is a component that analyze any actions or instructions you give to your computer and ensures that they are materialized in the system.

Why is this important on your computer? What types of processors are there? In this article you can learn more about this important component.

32 and 64 bit processor

The type of processor your computer may have will depend on the type of CPU. The processor capacity will determine how quickly your computer will channel all information and actions you take.

Therefore, the higher the number of bits, the easier and faster your computer will work. Most of the computers around the world have 32-bit processors.

Although they still remain, the presence of 64-bit processors since 2003 through the AMD company has set a trend and the number of computers with 32-bit processors (while still being widely used) has seen significantly reduced.

Processor of my PC

If your computer has been with you for a long time and you don't know what kind of processor it is using, finding out isn't very difficult. You must only access information di work of your computer as follows:

  • Right-click on the start menu of your computer.
  • Select the "System" option.
  • A window will open showing the full version of your computer. Among them, you will find the type of system.

Application version

These characteristics of computers have led to different versions of the same program. What is this for? It is precisely because software developers try to provide a better experience for their users.

Computers with processors a 64-bit speeds up your computer's operation much more, so there may be tools from a certain program that you might enjoy with this type of computer and not a 32-bit one

In search of differences

Despite having a virtually identical structure, the a 32 and 64 bit have few but important performance differences they may have on your computer. Here you can learn about some of the most relevant:


The margin of difference between one processor and another is quite large in the use of RAM. A 32-bit processor can only take advantage of 4GB of RAM, regardless of how much you may actually have installed on your computer.

On the other hand, the 64-bit processor can manage up to 16 exabytes, but there are no computers (at least for personal use) capable of working with such a scandalous memory.

Backwards compatibility

On the computers they use 64-bit processors, 32-bit applications can run without major problems. Of course, you can only use 32 or 64 bit programs, you can't mix them. On the other hand, programs with 64-bit versions are not supported on 32-bit systems.


In terms of heat generation in the computer, 32-bit processors they consume less energy and therefore they are less susceptible to heat generation in the CPU structure. However, this will also depend on certain elements such as the effectiveness of the ventilation system.


When you explore the market to buy a 32- or 64-bit processor, you will find that the former is much cheaper than the latter. Therefore, if your computer does not have major operating needs, it will help you to save.

Enhance the experience

Knowing the differences of each of the processors, it's just a matter of knowing what kind of processor your computer has. And if you are building a computer from scratch and intend to acquire a processor, you already have all the basics to choose which one to use.
