Well, the 4770 wasn't that popular because they were as rare as Bigfoot :p 

The 4890 replaced very very fast the 4870 and moved even into 4850 territory before they ran out from stores!

Either way ATI chooses, if they keep the awsome P/P ratio, there's going to be profit for them and great deals for us. Be it 28nm or tweaked core/arch, I hope it's a nice card for us 8)

Cheers!

The 4890 was reworked actually it has 3 million more transistors than the 4870 and idles at 40 watts less than a 4870. Plus it can overclock to above 1Ghz. If ATI refresh the 5870 to a 5890 i suspect they will do something similair and "upgrade" the memory to some of the 7Ghz capable GDDR5 that is now available. This would dramatically increase the GB/s on this card then to be paired with a reworked more efficent 5870 GPU it would beat everything currently available.

Honestly ATI could get away with a voltage bump and a nice OC on some better chips for the HD5890. ~15% better than the HD5870, would beat the GTX480 and possibly compete / perform directly under the GTX485.

I agree. Just go for the higher binned chips and they're fine. Maybe more memory bandwidth too and that would beat the GTX 480.

Well they've been binning for the HD5970. An HD5950 wouldn't require binned chips, as the HD5850 consumes a max of 153 watts, and that's only with Furmark.

I do remember people saying that they thought the 5870 was being held back by its memory bandwidth. No idea if this is true, but an effective 7GHz ram speed would certainly fix that.
