Graphics Processor: From Video Games to Cryptocurrencies and Artificial Intelligence

Graphics Processing Unit (GPU, from the English “Graphics Processing Unit”) — is a powerful specialized chip designed for lightning-fast processing of large volumes of data. In short, it is not just a component for video games, but a versatile tool for parallel computing, which today is used in the most unexpected fields — from neural networks to cryptocurrency mining.

How the GPU Became the Center of Attention

The late 1990s marked the emergence of the first graphics processors. Their main task was simple: to offload the central processor (CPU) from heavy graphics processing. At that time, video cards primarily handled 2D and 3D visualization, ensuring smooth gameplay and multimedia applications.

Two decades have passed — and everything has changed dramatically. Modern GPUs are equipped with thousands of cores capable of performing millions of operations simultaneously. This architecture has turned graphics cards into the core of high-performance systems: from gaming consoles to servers in data centers of major tech companies.

GPU and Cryptocurrency Mining

One of the most prominent chapters in the history of graphics processors is related to cryptocurrencies. When coins based on the Proof of Work (PoW) algorithm appeared, GPUs suddenly became an ideal tool for their mining.

What’s the essence? CPUs process tasks sequentially, step by step. GPUs, on the other hand, are specially designed to perform the same calculations billions of times in a row — exactly what is required in mining. Before Ethereum switched to the Proof of Stake algorithm, Ethash powered entire farms of video cards.

GPUs remain a popular choice among miners due to the balance between performance, price, and flexibility. Unlike specialized ASIC devices, graphics cards can be switched from one algorithm to another, making them a universal solution.

Revolution in Artificial Intelligence

But cryptocurrencies are just one side of the coin. The real revolution in GPUs has been in the field of AI and machine learning. When deep neural networks requiring the processing of billions of parameters appeared, GPUs became indispensable.

Major companies — from OpenAI to Google, from Tesla to Meta — use powerful graphics cards for training large language models, image processing, and speech recognition. The parallel architecture of GPUs is perfectly suited for such tasks, where each operation is independent of others.

Technical Foundations of GPUs

From a programming perspective, GPUs are used through specialized platforms. CUDA from NVIDIA and OpenCL are the main tools that allow developers to fully unlock the potential of graphics cards. These technologies provide direct access to thousands of computing cores, enabling acceleration by dozens of times compared to CPU computations.

The Graphics Card Market: Supply and Demand

At the consumer level, GPUs remain critically important for gaming, content creation, video editing, and virtual reality. NVIDIA and AMD constantly release new models with improved performance and energy efficiency.

Demand has sharply increased with the development of remote work, cloud services, and digital entertainment. At certain times, this has led to a shortage of graphics cards in the market, with prices soaring many times above retail.

The Future of GPUs

GPUs are no longer just components for graphics. They are the engines of modern computing. Today, graphics processors operate in a wide range of scenarios: from cryptocurrency farming to training next-generation artificial intelligence.

As machine learning algorithms become more complex and data processing needs grow, the role of GPUs will only strengthen. Graphics processors have transformed from specialized devices into universal computational accelerators, and this trend will only intensify.
