A graphics processing unit (GPU) is a type of computer processor that executes calculations quickly in order to produce graphics and images. Both business and consumer computers utilize GPUs. Despite their expanded use cases, GPUs are still typically used for rendering 2D and 3D pictures, animations, and videos.
The central processing unit (CPU) handled these calculations in the early days of computing. Yet, when graphics-intensive programs proliferated, the CPU’s workload increased, and performance suffered as a result. In order to free up CPU resources for other tasks and enhance 3D graphics rendering, GPUs were created. GPUs operate utilizing a technique known as parallel processing, in which different processors execute independent components of the same operation.
GPUs are well-known for enabling fluid, high-quality graphics rendering in PC (personal computer) games. Also, programmers started adopting GPUs to speed up workloads in fields like artificial intelligence (AI).
GPUs are used for what today?
Because current GPUs are more programmable than they were in the past, graphics chips are now being used for a wider range of jobs than they were originally intended for.
Examples of GPU use cases are as follows:
- GPUs can speed up the rendering of 2D and 3D graphics programs that are used in real-time.
- GPUs have improved video editing and video content development. The parallel processing of a GPU, for instance, can be used by graphic designers and video editors to speed up the rendering of high-definition video and graphics.
- In order to keep up with display technology like 4K and high refresh rates, emphasis has been placed on powerful GPUs. Video game visuals have gotten more computationally complex.
- GPUs are able to speed up machine learning. Workloads like image recognition can be improved using a GPU’s great computing power.
- Deep learning neural networks can be trained on GPUs, which can share CPU workloads. A neural network’s nodes each carry out calculations as part of an analytical model. Programmers finally understood that they could take advantage of far more parallelism than is achievable with ordinary CPUs by using the capability of GPUs to boost the performance of models across a deep learning matrix. Vendors of GPUs have taken note of this and now produce GPUs specifically for deep learning applications.
- Ethereum and other cryptocurrencies have also been mined using GPUs.
How Does GPU Work?
In the same electronic circuit as a CPU, a graphics card, the motherboard of a personal computer, or a server are all possible places to find a GPU. Construction-wise, GPUs and CPUs are fairly comparable. But GPUs are made expressly for carrying out more difficult geometrical and mathematical calculations. To render visuals, certain calculations are necessary. Transistors in GPUs could exceed those in a CPU.
GPUs will use parallel computing, in which different tasks are handled by different processors at the same time. For storing information about the images it processes, a GPU will also have its own RAM (random access memory). Information is stored about every pixel, including its location on the display. The image will be converted from a digital signal to an analog signal using a digital-to-analog converter (DAC) attached to the RAM so that the monitor can display it. Usually, video RAM runs at high speeds.
GPUs will come in two different flavors: integrated and discrete. While discrete GPUs can be put on a separate circuit board, integrated GPUs are integrated into the GPU itself.
Having GPUs fixed in the cloud may be a smart solution for businesses that need a lot of computational capacity, deal with machine learning, or create 3D visualizations. One example of this is Google’s Cloud GPUs, which offer potent GPUs on Google Cloud. The advantages of hosting GPUs in the cloud include the release of local resources and cost, time, and scalability savings. Customers have a variety of GPU types to choose from, and their needs can be met with flexible performance.
GPU & CPU
The designs of GPUs and CPUs are somewhat similar. GPUs are made primarily to render high-resolution graphics and video quickly, whereas CPUs are employed to respond to and process the fundamental instructions that run a computer. In essence, CPUs handle the majority of command interpretation, while GPUs concentrate on rendering graphics.
A GPU is often made for data parallelism and applying the same instruction to numerous data elements (SIMD). A CPU is built to do several operations and multiple tasks simultaneously.
The number of cores is another way that the two are different. The core is essentially the CPU’s internal processor. Although some CPUs contain up to 32 cores, the majority of CPU cores have a number between four and eight. A core may handle multiple tasks, or threads, at once. The number of threads can be substantially larger than the number of cores in some processors due to multithreading capabilities, which allow a single core to process two threads by practically dividing the core into two. Both transcoding and video editing may benefit from this. Two threads (separate instructions) per core are possible for CPUs (the independent processor units). Four to ten threads can be found in each GPU core.
Due to its parallel processing architecture, which enables it to carry out several calculations at once, a GPU renders images more quickly than a CPU. Although multicore processors can do calculations in parallel by integrating many CPUs onto one chip, a single CPU does not have this capability.
A CPU is frequently better suited to tackle simple computing tasks since it has a higher clock speed than a GPU, which enables it to complete calculations more quickly.

Customers may be drawn to capabilities like ray tracing, support for 4K, and 60 fps or more. In some cases, cost will be a deciding factor because some GPUs can cost twice as much while only providing 10%–15% higher performance.
GPU History
Since the 1970s, when video games first became popular, specialized processors have been available for processing visuals. A video card, a distinct dedicated circuit board, a silicon chip, and the appropriate cooling were initially used to perform 2D, 3D, and occasionally even general-purpose graphics processing (GPGPU) calculations for a computer. GPUs are the term used to describe contemporary graphics cards that have built-in computations for lighting, transformation, and triangle setup features for 3D applications. Higher-end GPUs, which were once uncommon, are now widely used and occasionally built directly into CPUs. Graphics card, display adapter, video adapter, video board, and nearly any combination of the words in these categories are some alternative terms.
In the late 1990s, high-performance enterprise computers started to use graphics processing units. The GeForce 256, the first GPU created especially for home computers, was made available by Nvidia in 1999.
Throughout time, additional resource-intensive jobs unrelated to graphics became more common thanks to the processing capability of GPUs. Early uses of GPU computing included scientific calculations and modeling; by the middle of the 2010s, machine learning and AI software were also powered by GPU computing.
In a virtual desktop infrastructure, Nvidia launched a virtualized GPU in 2012 that offloads graphics processing resources from the server CPU (VDI). Virtualized GPUs aim to solve the issue of poor graphics performance, which has historically been one of the most prominent complaints among users of virtual desktops and applications.
