A Graphics Processing Unit (GPU) is a high-performance processor originally designed to handle complex graphics and visual tasks. Over time, GPUs became widely used for artificial intelligence because they can process many calculations at the same time. As a result, GPUs are extremely effective for training and running modern AI models. Additionally, they are flexible, widely available, and supported across most AI frameworks, which makes them a go-to choice for developers and data-center operators.
How It Applies to Data Centers
GPUs play a major role in data centers because AI, machine learning, and large-scale compute workloads require massive parallel processing power. Therefore, AI-focused facilities often deploy large GPU clusters to accelerate training and improve inference performance. Furthermore, GPUs drive higher rack density and increased power and cooling requirements, influencing overall data-center design. As a result, sites hosting GPUs must support strong electrical infrastructure, advanced airflow systems, and sometimes liquid cooling. Additionally, GPUs remain essential for workloads ranging from generative AI to scientific research, making them one of the most in-demand compute resources in modern data centers.
