What is a CPU?

To see the difference between these three components, the Central Processing Unit (CPU) is something you must understand first. The main task of the CPU is to handle almost all tasks and calculations performed on all the hardware that is embedded in a computer. Easy language, the CPU can be likened to the brain of your computer.

CPU capability can be measured by several factors. First, how much is the 'core processor' of a processor. Generally, a modern processor comes with at least two core processors. Not infrequently they have Hyper Threading capabilities that make one core able to run two processes simultaneously.

There is also a measure of processor speed measured in gigahertz (GHz). For example, if the CPU has a speed of 2.4 GHz, then this CPU can process up to 2.4 billion instructions in one second.

Currently, the CPU market is controlled by two large manufacturers, namely Intel and Advanced Micro Devices, otherwise known as AMD.

What is a GPU?

Almost the same as the CPU, Graphic Processing Unit (GPU) is also one of the important components in a computer. If the CPU processes all data related to running instructions to run a computer, the GPU processes the instructions sent by a software to display on the screen.

Usually, there are two types of GPUs. First, a directly integrated GPU that is often referred to as a discrete GPU. Other GPUs that must be pinned to the motherboard are usually called external GPUs.

In modern computing, the GPU does not only display 2-dimensional images, such as displaying a GUI and others. The GPU is currently intended to process a 3-dimensional image, either in a game or in a computer-aided design (CAD) software. In addition, at this time a GPU can also make someone able to enter the world of Virtual Reality (VR).
