what is GPU

A Graphics Processing Unit (GPU) is a specialized electronic circuit designed to efficiently manipulate and render images, animations, and videos for display on a screen. Unlike CPUs, which are optimized for sequential processing, GPUs excel at parallel processing, with thousands of smaller cores working together to execute tasks simultaneously. This parallelism enables GPUs to handle complex graphics rendering tasks, such as geometric transformations, rasterization, and shading, with remarkable speed and efficiency.

GPUs have their own dedicated memory, separate from the system RAM, and utilize various levels of caches and memory types to optimize data access patterns. In addition to graphics rendering, GPUs are increasingly used for general-purpose computing tasks through frameworks like CUDA and OpenCL, allowing them to accelerate scientific simulations, machine learning algorithms, and other computationally intensive tasks.

Graphics APIs such as DirectX, OpenGL, and Vulkan provide developers with the tools to interact with GPUs and harness their capabilities for creating immersive graphics experiences and high-performance computing applications. Overall, GPUs play a critical role in modern computing, powering a wide range of applications from gaming to scientific research and artificial intelligence.
