Correct me if I'm wrong, but isn't the 4890 supposed to be just an overclocked 4870?

That is the word on the grapevine, yes. In fact, I think it says that in the article...

The card has a diffrent pin out to the 4870 core, it is a derivative with enhancements and its going to have 850mhz core aparently and 4x975 memory. Those are likely to get lower though.

I hope they've sorted out some way of dropping voltage to the DDR5 chips when idle - that would help in the power usage department.

It would also help with the temperatures. It doesn't really help that the memory is running at 3.6ghz all the time .

no interest to me in itself, but hopefully it will tease the price of the other 48xx's down just a touch
