What’s GPU? Definition and explanation

The term GPU often arises in connection with the PC, the CPU or the graphics card. This is not a spelling mistake, because the GPU is different from the CPU. We explain in this guide, which is a GPU and what it does.

What's GPU? Definition and explanation

The abbreviation GPU is advertised for the term graphics processing unit. A GPU is also a processor such as the CPU, but it is optimized for graphics computation on PCs, consoles, smartphones, tablets and Co. a GPU so is the graphics processor of a device.

  • What is a CPU with the PC? What makes the processor?

The GPU calculates the pixels displayed on your screen or display. This includes 2D and 3D graphics. Today's PC processors usually have integrated a GPU as a graphics unit. Through them, the actual processor (CPU) is relieved that calculates everything else that has nothing to do with the image. Who does not have GPU on the CPU, you need a graphics card to display images on the monitor.

The GPU calculates the graphics as opposed to CPU: At a resolution of 1920 x 1080 pixels which are precisely that number of pixels: 2,073,600 pixels so. With a screen with 60 Hertz, they done that 60 times per second, per second are a total of 124,416,000 pixels calculated (approximately 124 million).

The larger the screen resolution, the more pixels must calculate the GPU. Unless the CPU with the GPU is not very powerful, the graphic calculation can then begin to stutter at high resolutions and to falter.

In older PC systems the CPU nor does a lot of the graphics calculations. In programs such as VLC Media Player or the editing program Adobe Premiere, the GPU acceleration can be activated later.

Where is the GPU?

Today's multi-core processors have integrated alongside their CPU cores and the GPU. Therefore, processors such as the Intel Core i3, i5 or i7 series is also referred to as heterogeneous processors. &Heterogeneous; # 8220&# 8221; means as much here as &# 8220; internally structured&# 8221 ;. The GPU therefore be found on the silicon chip - called the - of CPUs on which all transistors are housed. but the GPU can sit on the motherboard.

Who has a heterogeneous CPU, does not necessarily need a graphics card. However, graphics cards are more powerful than the on-board versions and can also have multiple GPUs. Who still uses an old CPU without GPU, need necessarily a graphics card for display output.
