Retina
When an Apple product has a Retina display, each user interface widget is doubled in width and height to compensate for the smaller pixels. Apple calls this mode HiDPI mode. In simpler words, it is one logical pixel = four physical pixels at the very beginning. The advantage of this equation is that the CPU "sees" a small portion of the data and calculates the relative positions of each element, and the GPU renders these elements with high quality assets to make the output much sharper and clearer. The goal of Retina displays is to make the text and images being displayed extremely crisp, so that pixels are not visible to the naked eye or at viewing distance. This allows displays to rival the smooth curves and sharpness of printed text and immediacy of photographic prints.

Retina displays use 200% DPI scaling by default, w HiDPI mode. In simpler words, it is one logical pixel = four physical pixels at the very beginning.
