n. “A graphics processor built directly into the CPU or system-on-chip.”

iGPU, short for integrated Graphics Processing Unit, refers to a graphics processor that is embedded within a CPU or system-on-chip rather than existing as a separate, dedicated graphics card. Unlike discrete GPUs, an iGPU shares system resources such as memory and power with the CPU.

The primary goal of an iGPU is efficiency. By integrating graphics processing directly into the processor package, systems can reduce cost, power consumption, heat output, and physical size while still providing capable graphical performance for everyday tasks.

Modern iGPUs are far more than simple display adapters. They support hardware-accelerated video decoding, 3D rendering, multi-monitor output, and even light gaming or compute workloads. In many laptops, desktops, and mobile devices, the iGPU handles all graphics duties without the need for a discrete GPU.

n. “The perception or representation of objects with depth, height, and width.”

3D, short for three-dimensional, refers to any object, environment, or representation that has length, width, and depth, allowing for realistic perception of volume and space. In computing and media, 3D is widely used in graphics, modeling, printing, and animation to create lifelike visuals and immersive experiences.
