Active GPU #

The CPU & GPU menu item can display which GPU is active. This is handy, because some Macs have more than one GPU. The active GPU represented by a single letter — if an “N” is displayed, that means the nVidia GPU is being used. Here’s a full list of the possibilities (what’s shown will depend on your Mac model):

  • I = Intel or integrated.
  • D = Discrete.
  • A = ATi.
  • N = nVidia.

We include integrated and discrete as well as ATi and nVidia, because in some cases, the integrated and discrete GPU comes from the same manufacturer.

We’re hoping to expand this help page soon.
