Should we warn drunkenmaster and the 80% speed increase people to take cover now ?

Hate to say I told you so.
ACtually I've said many many times in the past that generally speaking you'd be comparing non refresh products, you can go back and Look, I've been saying that for 5 years, 4870 vs 5870 is a fairer comparison and gave you around the 80% mark. 7970 over 5870 is both, double the transistors, 5870 is 2.15billion, 7970 is 4.3billion, Cayman is 2.64billion.
It IS 80% faster than the 5870, its even more than 80% faster in many cases.
Its actually hugely faster than the 6970 in many cases, unfortunately its best speed comes in eyefinity, which will always be a very niche product simply because most people won't buy 3 screens, won't set up 3 screens with an angle, have a desk that can comftably use 3 screens or want to, I don't want to either. 3d performance I will be very interested in as one screen + 3d is FAR more appealing than 3 screens in the space I don't have for them, though 3d isn't as appealing as 120hz.
Where AMD went wrong is ignoring performance at 1080p/1600p for performance less than 5% of top end kit buyers will be using.
Also, the price.......... oh well, I was wrong on the price, but personally I think it hasn't been helped by peoples attitude........ we've had 6 months of people talking about new gen and how it will be expensive. If we had 6 months of people saying on every forum worldwide you'd never pay more than £350 for a card, it would likely never have gone beyond £350.
We'll also have to see where prices end up in a month or two, and when the GK104 launches.
As for yields, I don't think that has much to do with it, AMD are advertising 1Ghz clocks with ease, stock heatsink is hitting 1.1Ghz+ good heatsinks will likely hit well beyond that, it could be a monster at higher clock speeds without extreme cooling. I've yet to see proof yields are bad, capacity on a process and yields are NOT the same thing, not even close.
Price though, at £300 its a genuine 80% faster than 5870 card at the same price point on a new process, randomly being sold at £420-500(seen pretty much all prices listed now in reviews) its a bit of a joke. This is coming across as a new CEO with a new plan and that is to milk as much money as they can, but I get the feeling in doing so they'll be losing more customers and sales than they make with higher prices.
Oh, and techpowerup have been AWFUL for donkeys years now, COD 4, the first one, as a performance benchmark which just luckily pushes the 6990 right into the 580gtx, removed all of AMD's best games, disabled xfire in the one game AMD excelled in then finally removed that game.
Their % comparisons are literally worthless as they've added more and more completely CPU limited games and come up with both the least fair and the least relevant benchmarking suite of essentially any website out there.
A 590gtx is less than 20% ahead of a 580gtx, a 6990 the same, its laughable how badly they've ruined the site with CPU limited rubbish, COD 4 and World of warcraft.
If you simply go through and throw out the CPU limited benchmarks to get a fairer comparison you won't get anything even remotely close to those final numbers.
