Internal Graphics
The Intel Core i7-1255UL has integrated graphics, called iGPU for short. Specifically, the Intel Core i7-1255UL uses the Intel Iris Xe Graphics 96 (Alder Lake), which has 768 texture shaders and 96 execution units. The iGPU uses the system's main memory as graphics memory and sits on the processor's die.
A photo or video codec that is accelerated in hardware can greatly accelerate the working speed of a processor and extend the battery life of notebooks or smartphones when playing videos.
