Red giants are more luminous, white dwarfs are hotter.
Temperature:
Red giants ~2500 - 3000K
White dwarfs ~5000 -100000K (two to 33 times hotter)
Luminosity:
Red giants ~100 times as bright as our sun
White dwarfs ~ 1/10000th as bright as our sun
Good reference below. See the Hertzsprung-Russel diagram.

Well I know you are talking about stars. There are a whole family of star types, some progressing from one to the next, during their lifespan ( the Main Sequence). To answer your question, white dwarfs are about twice as hot and a 100 times more luminous than red giants. See the link below for a good overview.
