GPU stands for Graphics Processing Unit. A GPU is a specifically designed circuitry chipset that does the work of rendering high-pixelated images and 3D representations on the computer screen.
A GPU offers graphical bootup on the screen in a much lesser time, especially for the gaming enthusiasts who need a fast rendering of objects and figures in their game.
In some computers and laptops, GPUs can be offered as integrated with the CPU’s processor circuit and in some cases, it is given separately as a video or Graphics card.
It is seen that the GPUs when given separately, the computer does a much better job in terms of image and object rendering as compared to the integrated GPUs.
Due to the availability of separated graphics cards or GPU, the processor remains engaged with other important tasks and thereby offers much better performance to the user in terms of gaming and other video-related tasks.
A GPU (Graphics Processing Unit) comes into play only when you plug it into a PCIe (PCI express) slot, once it is fastened up with the slot it becomes a component of the motherboard and offers all its benefits to the users.
The GPU plays an essential role in the overall appearance and visual graphics of the computer, fine functions and decrypting of animations and visual effects, 2-dimensional rendering, basic zooming, and expansion as well.
It must be clear that the more advanced your GPU is, the better and finer your color and object resolution will be. Dedicated graphic cards come with their own memory space which does not put the load on the main memory or RAM of the system while working.
Whereas, if you look at the integrated GPU they don’t have their own memory they share and take help from the system memory to execute operations while working.
The main purpose of developing the GPUs was to improve the rendering process of the 3-dimensional objects that appeared on the computer screen. However, as time passed the GPUs became more advanced, and now they can be programmed by the makers for better and enhanced performance in terms of rendering power.
These advancements somehow helped VFX guys and animators to create amazing designs and videos having realistic colors scheme, lighting, and different shadows without any hassle.
Why GPU is important for playing Games?
The computer games that we see today are not as convenient as we used to see earlier. Hyper-intensive colors, super-realistic in-game world, variety of features, and other additional specifications.
All of these combined with an ultra-modern display like the 4K one and super-fast refresh rates (at least 90 FPS), everything makes it quite tough for the standard or inbuilt (integrated) GPU to cope with.
This is where the need for a GPU (discrete) comes into play which makes everything easier and sorted by ultimately reducing the workload of the CPU as well and providing a beautiful gaming experience to the users.
What is more important for video editing, CPU or GPU?
This thing totally depends on what kind of software or application you are using for the purpose of video editing. Many of the video-creating/editing software including Sony’s Vegas Pro and the DaVinci Resolve is seen to be consuming the GPU more as compared to the CPU. Whereas, if you look at the editing software like Adobe’s premier pro it consumes more from your CPU than the GPU. Maybe, due to the fact that it is less advanced than Sony.
The second most important factor which decides whether the CPU consumption is more or the GPU consumption is the way of editing.
Like, if you are just cutting, trimming, or doing normal crafting work, it will only use your CPU, but if there is a lot of extra technical stabilization, color grading, layering, and transitions, etc will definitely make use of the GPU.
Also, the inclusion of multi-dimensional graphics and effects is a GPU-intensive task, unnecessarily accelerating the encoding performance while exporting the timeline is also a GPU-consuming task, but simple encoding of video or mp4 format will only be done on the CPU of the computer.
