GPU
1. GPU definition A GPU (Graphics Processing Unit) is a massively parallel processor optimized for high‑throughput, data‑parallel workloads. Originally designed for rasterization and pixel shading, modern GPUs accelerate gaming graphics, real‑time ray tracing, video processing, scientific compute, and neural network training/inference. 2.
