What is GPU Acceleration?
GPU acceleration means running computation on a graphics card instead of the main processor. A CPU has a handful of powerful cores working sequentially; a GPU has thousands of smaller cores working in parallel — ideal for AI and video work, where the same mathematics repeats across millions of pixels. Tasks that take a CPU hours can finish on a GPU in minutes.
For video AI this is the difference between practical and impossible: analysing a week of CCTV footage with object detection might take days on CPU but hours on a mid-range NVIDIA card. In Indian terms, a used GTX or RTX card worth ₹15,000 to ₹50,000 turns an ordinary desktop into a capable analysis workstation, while cloud GPUs rent by the hour for occasional heavy jobs.
