The 6950 has come down as low as £612.
So if AMD releases anything with worse performance at £550-600 people won't buy it.
Though given the state of things it would not completely surprise me if it happened
You can’t compare dumping prices to new prices.
6950’s are been dumped at huge discounts, which is miles below the MSRP.
I would personally love to see AMD rebrand the 6950XT as 7800 XT with a $649 price tag as they’d literally sell thousands of them, but whether the 7800 XT is all new or a rebranded 6950 is total unknown.
At same time don’t be disappointed at all if the card was $699 or $599 it’s an unknown depending on how aggressive AMD want to be if they can produce volume or not.
