does GPUs have multiple cores like CPUs?

Never really knew this question but with mobiles having quad core GPUs these days it got me thinking surely desktop PC GPUs must be like that or better these days. But I'm unsure. The only thing I know is 690 cards etc have 2 GPUs in but that's actually full cores. Not 1 GPU with multiple cores. Is it.

Are GPUs single core and if so why hasn't GPUs gone the same way as CPUs being multi core. If they already are and this is a daft question then nvm and ignore.

Hmm I see so they are as powerful as multi core would have been but keeping with a single core design then.
