Energy Efficient GPU?

[weEvil]

How do the Alienware laptops have such high-end GPUs in them? I've seen a model that even has SLi.

Are they using some low power version of the current GPUs? Like there are Low-Power CPUs that deliver the same performance. Is there such an equivalent for a GPU?

The new cards are absolute hogs from what I see. Plus all that power running through the system produces a lot of heat.

They use mobile versions of the GPUs. They aren't as powerful as their desktop counterparts, but still quite good for gaming on the go.

and they still use an insane amount of power. you cant game without a plug, the battery will drain sooo fast.
