Introduction
In today’s complex tech world, a lot of abbreviations like CPU, RAM, and HDD are terms that have probably been in our minds for quite some time now. Yet, do we really know what they all mean? In this blog, we will be covering what GPU is. Thus, although its existence might make something along the lines of high-performance e-gaming PCs first come to your mind, the role of the GPU is far greater and encompasses very much more than creating realistic processing value. Well, let’s hold on tight while we take a detailed insight about what is GPU, what is the full form of GPU, its evolution and more in this blog.
GPU Definition
The GPU full form is Graphics Processing Unit. To define GPU accurately, it is a hardware component used primarily for high-speed graphics processing and parallel computations. GPUs are also called Graphics Processing Units, graphic cards, or video cards. Traditional GPUs originated with the purpose of enhancing frame rates in video games and Computer-Aided Design (CAD). They can handle large chunks of data at the same time, and this makes them be used in other applications where similar mathematical computations are needed, such as machine learning, video processing/creation, and artificial gaming. One important aspect is that GPUs are best utilized when working in parallel since their strength is in repetitious mathematical computation. If you have understood what does GPU stands for, let’s decode its evolution.
History of the GPU
The actual history of the GPU goes back to the late 1960s and early 1970s, a time when computer graphics, or rather the lack of them, needed to be more logical. This means that the past technologies that gave the world blocky pixels forming what could be called primitive shapes were the epitome of advancement. When computers were first introduced, they were not capable of handling the calculation involved in enough processing to get quality animation. This brings us to the next device called the GPU or the graphic processing unit; this device helps reduce the workload on the CPU, particularly with regard to graphical processing.
Originally, the GPU working was configured to perform designated graphical operations such as rendering of lines and polygons. It relieved the CPU from performing a load of work as required in the PCSX system, which in return increased the overall graphical performance. It was a game changer, literally, for people behind the gaming industry to produce much more intricate games than before, hence cultivating the video games as we know them today.
But what makes the GPU so good at it, and why is it considered better and more optimal for certain tasks than the CPU? Architecture is the key to success in this case. Also, unlike the CPU, which is built to handle tasks one after the other (and referred to as being ‘instruction based’), the GPU excels at handling concurrent tasks.
All these computations are possible because of what is in the GPU. One of them that stands out in the performance is that it has a large number of cores, some of which are dedicated to handling some graphical calculations. These cores are operative in parallel, and these are the ones that perform data calculations at an incredibly high speed. It is best suited for applications such as rendering large scenes in 3D, where thousands of calculations must be done on each frame.
What are the Different Types of GPUs?
As an essential component in modern computing, Graphics Processing Units, or GPUs have evolved so that they can meet the increasing demands of various applications. Resultant, 3 different types of GPU are available. Understanding them is essential so that you can select the right technology for your needs such as gaming, content creation, or advanced computational tasks like machine learning.
Discrete GPUs
A discrete GPU (known as a dedicated GPU) is a separate chip from the CPU. It includes its own video memory, or VRAM and due to this separation, GPU can handle complex tasks. It can render high-quality graphics without relying on the system’s main memory. Further, discrete GPUs are known for delivering superior performance because of this independence. Mainly, it can support graphics-intensive applications like video editing, gaming, and 3D rendering. However, they consume more power, generate more heat, and often require advanced cooling solutions. Still, they are a top choice for users needing robust GPU capabilities; even for AI and machine learning tasks.
Integrated GPUs
Integrated Graphics Processing Unit (iGPU) is built directly into the CPU. It shares power and memory with the CPU so it is a more energy-efficient option. However, integrated GPUs may lack in offering the same level of performance as their discrete counterparts. They are ideal for everyday computing tasks like laptops and smaller devices; power efficiency and size are essential factors in such tasks. It is popular as it can combine GPU and CPU functions on a single chip and more compact and efficient systems. Therefore, iGPUs are a common feature in many modern computers that require moderate workloads and mobile computing.
Virtual GPUs
Cloud computing has raised Virtual GPUs (vGPUs) as a versatile option that can replicate the capabilities of both discrete and integrated GPUs. It operates entirely through software on cloud GPU servers. The advantage of virtual GPUs is that they eliminate the need for physical hardware and offer a more cost-effective and maintenance-free solution. vGPUs are particularly useful in cloud environments where multiple users can share GPU resources for various workloads like graphic design, machine learning, and AI applications.

What’s Inside the GPU?
As we have seen what is a GPU and why it is essential, it is time to know how it is. The following outlines the crucial parts of the system that will give you an understanding of how does a GPU work.
- Streaming Multiprocessors (SMs): These are the soul of the GPU; there are many cores that work on the graphical data.
- Tensor Cores and RT Cores (Optional): These are specialized cores present in most modern graphic cards to perform highly specific functions such as ray tracing and AI.
- Video Memory (VRAM): This is a type of RAM that holds the graphical information in a format that is easily accessible to the GPU for carving.
- Video Output Interface: This interface enables the GPU to communicate with the display and sends out the final rendered image of the screen to the monitor.
The individual effectiveness and capabilities of such components depend on the particular GPU model and its users’ requirements. When it comes to gaming GPUs, manufacturers concentrate on computed graphical competency, while professional GPUs can contain focused cores for applications such as video editing.
GPU vs Graphics Card
A GPU is a graphics processor that is usually integrated into a computer, while a graphics card is a hardware component that needs to be installed into a computer. Interestingly, people often mistakenly consider both the names, that is a graphics processing unit and the graphics card, as having one and the same meaning but it’s different.
Graphics cards are an Advanced Interface Board (AIB) that are inserted into a slot in the computer system’s central processing unit. Graphics cards, as a component of a computer, do not reside within the frame of the computer; they are rather cards that can easily be replaced. GPU is a feature that is used whenever you buy or build a graphics card.
The GPU is the only component that is found more densely in graphics cards. It coexists with other elements, such as video RAM, or VRAM, for video storage and other parts like the HDMI or Display Port for signal transmission and a cooler. However, a GPU can also be on the motherboard, or it may be done with an all-in-one chip solution for the rest of the parts.
Decoding Different GPU Technologies
Streaming Multiprocessors (SMs)
Picture a facility with a wide range of sectors and a highly populated area. That is the simplified concept of an SM. An SM is central to a GPU and contains several elements of a RISC processor. They cater to a plethora of cores, and each is highly skilled at managing particular graphical or computational processes. This helps in the dispersion of workload essential for the GPU, which always results in tasks being accomplished faster compared to a CPU with fewer cores.
Unified Memory Architecture (UMA)
In the past, the CPU and the GPU had their own individual memory pool through which they could access assets. UMA narrows this divide, thereby improving access to a single comprehensive memory that is available to both processors. It thus cuts the number of transfers of having to copy data back and forth, therefore increasing performance.
Shader Model
The shader model can be described as hardware-dependent instructions for the GPU that are available to the developer. It determines how the GPU will handle various kinds of graphical data – lighting, textures, and specific effects. Indeed, each new version of shader models brings a whole plethora of improvements that extend GPU’s abilities to render increasingly realistic and detailed images.
