GPU
Graphics processing unit optimized for parallel computation, often used to accelerate machine learning and AI tasks.
📖 GPU Overview
A GPU (Graphics Processing Unit) is a hardware chip designed for parallel computations, originally developed for graphics rendering in gaming and visualization.
GPUs are used in artificial intelligence, machine learning, scientific computing, and high-performance computing (HPC) to perform thousands of operations simultaneously.
They are optimized for matrix operations, neural network training, and large-scale data processing, providing higher throughput than CPUs for tasks suited to parallelization.
