What is GPU? Definition and explanation


The term GPU often appears in connection with the PC, the CPU or the graphics card. This is not a spelling error because the GPU is different from the CPU. We explain in this guide what a GPU is and what it does. Video | Mythbusters: GPU versus CPU What is GPU? Definition and Explanation The abbreviation GPU is pending for the term Graphics Processing Unit. A GPU is also a processor like the CPU, but it is optimized for the graphics calculation of PCs, consoles, smartphones, tablets and Co. A GPU is thus the graphics processor of a device. What is a CPU on the PC? What does the processor do? The GPU calculates the displayed pixels on your screen or display. This includes 2D and 3D graphics. Today’s PC processors have mostly integrated a GPU as a graphics unit. It relieves the actual processor (CPU), which calculates everything else that has nothing to do with the graphics. If you do not have a GPU on the CPU, you need a graphics card to display images on the monitor. What is GPU VRM? Software that monitors the temperature of your graphics card often also displays the entry “GPU VRM”. The VRM (Voltage Regulator Module) stands for the voltage converter of the graphics card. They are also called “Mosfets”. They are under the elongated passive cooler at the end of the graphics card.GPU and CPU: Differences in comparison The GPU calculates the graphic in contrast to the CPU: At a resolution of 1920 x 1080 pixels, this is precisely this number of pixels: 2,073,600 Pixel. On a 60 Hertz screen, it does that 60 times per second, so a total of 124,416,000 pixels per second are calculated (around 124 million). Here we explain the unit Hertz: Refresh rate: 100, 200, 800 – How much Hertz does a TV need? The larger the display resolution, the more pixels the GPU needs to calculate. If the CPU with the GPU is not very powerful, the graphics calculation can then start to jerk and stagnate at high resolutions. In older PC systems, the CPU still handles a large part of the graphics calculations. In programs such as the VLC Media Player or editing program Adobe Premiere, the GPU acceleration can be activated later. Where is the GPU? Today’s multicore processors have integrated the GPU in addition to their CPU cores. Therefore, processors such as the Intel Core i3, i5 or i7 series are also referred to as heterogeneous processors. “Heterogeneous” here means “internally structured”. So you can find the GPU on the silicon chip – the so-called die – of CPUs, which also houses all the transistors. The GPU can also sit on the motherboard. How does a transistor work? (English video).

However, graphics cards are more powerful than the on-board variants and can also have multiple GPUs. If you are still using an old CPU without GPU, you will need a graphics card for the screen output. Install graphics card – That’s how it works
