A Graphics Processing Unit GPU is a specialized electronic circuit designed to accelerate graphics rendering and complex computations required in modern multimedia, gaming, scientific simulations, and artificial intelligence. Unlike a Central Processing Unit (CPU), which is optimized for serial tasks, a GPU excels at parallel processing, handling thousands of operations simultaneously for high efficiency in graphics-intensive applications graphics processing units GPU .
Modern GPUs consist of thousands of small cores (CUDA cores for NVIDIA, Stream Processors for AMD) that handle rendering of textures, lighting, shading, and geometry transformations. They support advanced technologies like real-time ray tracing which simulates light behavior for photorealistic visuals. With AI cores (Tensor Cores), GPUs also improve deep learning tasks such as image generation and video enhancement.
The memory (VRAM) in GPUs, typically GDDR6 or newer variants like GDDR6X and HBM2, provides the bandwidth to feed these cores with raw data rapidly. VRAM capacity can range from 4GB (entry-level) to 32GB+ (high-end), crucial for gaming at 4K resolution, professional 3D modeling, and video rendering workflows
