Pixel rate refers to the number of pixels that a GPU can render onto a screen every second.
Digital images are made up of pixels. If you zoom in far enough on an image, you’ll notice that it’s just a bunch of pixels or squares. To process an image on a digital device such as a desktop computer or laptop, a GPU (graphics processing unit) needs to write to the local memory.
Certain graphics cards can write faster than others, which shows in the pixel rate, measured in GPixel/s. A graphics card like the Nvidia Quadro GV100, for example, has a pixel rate of 208.4 GPixel/s while the Zotac Gaming GeForce RTX 2080 Ti AMP Extreme Core has a pixel rate of 154.4 GPixel/s.
The result? A higher screen resolution, especially for image-dependent graphics needed to support activities such as gaming and video editing.
