Multi-Core GPU

Hi All,

After reading about the RX 480 it got me thinking...

Why don't AMD or NVIDIA to multi-core GPU's in a similar fashion to what is happening in CPU architecture?

Would there be limiting factors in terms of the message bus or bandwidth?

AMD have developed a really cheap card with good performance on its own and then have the option for 2 cards in sli to match 1 GTX 1080.

So why not just do a dual core RX 480? Why wouldn't NVIDIA to a dual core GTX 1080?

Apologies if this is a really stupid question.

So why didnt AMD do a dual core RX 480 (lets call it a RX 490) so they have a single card that can match the GTX 1080? Or is that something they will do further down the line to extend the lifecycle of the product?
