A Graphics Processing Unit (GPU) is a specialized electronic circuit designed to accelerate the processing of images, videos, and complex computations. Created to render graphics in real time for video games, GPUs have evolved into essential components in modern information technology (IT) systems. Today, they power everything from gaming rigs and content creation tools to artificial intelligence (AI), machine learning (ML), and large-scale data analytics platforms.
In the IT industry, GPUs are not merely graphics cards; they are powerful parallel processors capable of handling thousands of simultaneous operations. This capability makes them ideal for computationally intensive tasks and has led to their adoption across high-performance computing (HPC), cloud computing, data science, and blockchain applications.
The first GPU-like processors were integrated graphics chips on motherboards. In 1999, NVIDIA introduced the term “GPU” with the launch of the GeForce 256, the first processor to offload 3D graphics processing from the CPU.
A modern Graphics Processing Unit comprises thousands of cores organized into smaller processing units called streaming multiprocessors (SMs). Unlike CPUs, which are designed for serial tasks, GPUs are optimized for parallel processing, making them more efficient for tasks that involve large-scale matrix operations or repetitive data tasks.
