Graphics Processing Unit: Powering the Global AI and Digital Economy

Nvidia Corporation, creator of the first GPU in 1999, is in focus as GPUs now power the global digital and AI economy.

  • However, NVIDIA does not legally hold a monopoly, but it enjoys near-dominant market power in certain GPU segments, especially AI computing.
    • It holds around 90% market share in discrete Personal Computer GPUs and maintains a strong position in data centre GPUs. 

About Graphics Processing Unit

  • A Graphics Processing Unit (GPU) is a specialised processor designed to perform many simple calculations simultaneously (parallel processing).

What are Neural Networks?

  • Neural Networks are computer algorithms inspired by the structure and functioning of the human brain, designed to recognize patterns, learn from data, and make decisions.
  • They form the foundation of Artificial Intelligence (AI) and Machine Learning (ML) systems.

Why do Neural networks use GPUs?

  • Neural networks can run on CPUs or GPUs, but engineers prefer GPUs because the networks run many tasks in parallel and move a lot of data.

  • Unlike a CPU (Central Processing Unit), which handles complex, sequential tasks, a GPU is optimised for large-scale repetitive computations.
  • Initially developed for video game graphics, GPUs are now central to AI, data centres, simulations, and high-performance computing (HPC).
  • Major manufacturers include: NVIDIA, AMD and Intel

Origin & Evolution

  • In 1999 NVIDIA launched GeForce 256, marketed as the world’s first GPU, initially for video games.
  • Over 25 years, GPUs have moved from graphics rendering to becoming core infrastructure of the digital economy.
  • Today, GPUs are indispensable for AI, machine learning, simulations, and high-performance computing.

Applications of GPU

  • Artificial Intelligence & Deep Learning: GPUs are used for training and deploying AI models because they efficiently handle large-scale parallel computations.
    • For example: Models developed by OpenAI are trained using GPU clusters.
  • Scientific Research & Supercomputing: GPUs accelerate complex scientific simulations such as climate modelling, genomics, and molecular dynamics; many supercomputers use GPUs developed by NVIDIA.
  • Gaming & Graphics Rendering: GPUs were originally designed for rendering high-quality 3D graphics, enabling real-time gaming, virtual reality, and ray tracing technologies.
  • Autonomous Vehicles: GPUs process real-time sensor and camera data in self-driving cars, enabling object detection, path planning, and decision-making systems.
  • Cloud Computing & Big Data: GPUs power AI-as-a-Service platforms and data analytics, where cloud providers deploy GPU-enabled servers to accelerate machine learning workloads.

Difference between GPU vs Graphics Card

Aspect GPU (Graphics Processing Unit) Graphics Card (Video Card)
Definition A specialized processor designed for parallel computation and graphics processing A hardware device that contains the GPU and enables graphics output
Nature A single processing chip A complete hardware unit installed in a computer
Main Function Performs mathematical computations for rendering, AI, and parallel tasks Provides display output and supports GPU-accelerated tasks
Independence Cannot function alone; requires integration into a system Functions as a plug-and-play device in desktops/servers
Use Case Core computation engine for AI, gaming, and simulations Used in computers for gaming, professional graphics, and AI workloads
Example GPU chip inside advanced processors like those from NVIDIA Graphics cards such as RTX or Radeon series installed in PCs
