Its very safe to say Flagship dual cards will cost a ludricous £4-500 or more they have done for many many previous generations.
single card £300
Mid range are always around £200
These prices have been accepted by the consumer now. It doesnt matter if the yields are super 99%.
Yup, because there were never £300 expensive cards before the 4870 at all, nope. LIkewise £400 is ludicrous, for two cores and two sets of memory that individually cost, errm, £200 each.... thats crazy I tell you.
Nvidia, another matter.
Pricing WILL depend on the design of the core and how big it is coupled with how good yields are. Another 4870, and by that I mean circa 250mm2 card and a great 28nm process and the top end card will not cost £300, another closer to 400mm2 card, with a poor process, you'd be lucky for it to be under £300.
Its really very simple, yields effect price, in every single semiconductor based product worldwide.
IF a $5 wafer gets you 30 working chips, or 100, it effects price, if you can't see why, then its really not worth going into.
Theres a reason why Barts + decent yields cost the same as 4850's did, similar size, similar cost. Theres a reason a 334mm2 Cypress cost £300 at launch and a 389mm2 Cayman cost £275 at launch, yields.
The question for 28nm will be, are both companies going with two gens at 28nm(more to do with when 20-22nm is due than anything else) or are they going for one "proper" gen and one fairly big high end core and hope 20-22nm is on target.
If the former, its quite likely they'll go for something quite small to start with, which will also likely be comparitively cheap.
