Definition

A GPU, or Graphics Processing Unit, is a specialized processor designed to accelerate graphics rendering and perform complex calculations required for visual output. It is highly parallel in nature, meaning it can process many tasks simultaneously, making it particularly effective for matrix-matrix multiplication where numerous operations can be performed in parallel across multiple data points.
