If the performance rumours are true the 285X will be more like a GTX 780
If the 285 with 1792 SP's @ 920Mhz is 280X level performance then a 285X with 2048 SP's @ 1000Mhz? is going to be kicking a 780's heels, if not match it.

Endless milking 
AMD themselves have pitted the 285 up against the 760, to think that the 285x will go against the 780 is farcically wishful thinking.

Price point wise I doubt it.
The 285 would be priced at around £180 or there about, where as for Nvidia, the GTX870 would be at least £320~£350 going by the x70 of the pass few gens, and the GTX860 (if it ever get released) would most probably be at around £220-£240 price point.
The slide in kaaps op says 'up to' 15% quicker then a 760, that's absolutely no where near a 780/290.
Likely clipping the heels of a 770/280x, but probably not quite there, if it was then they'd be doing 285 vs 770 slides, especially given the 770's still retarded pricing.
Any word on pricing of these? Presume if it's being pitted against the 760 then it will be around £150? The lower the price the better tbh, despite being the newer feature packed gcn 1.1, it would still be hard to recommend over a 280.
Edit: Will there be a 285 & 285x?

Well its all speculation, and Kaaps rumours could be utter rubbish, having said that i think you missed my response to you here.
If this GPU is based on Hawaii (290/X), its not unbelievable for it to surpass Tahiti's performance per clock / Stream Processor, personally i have always suspected Hawaii does, it scales at least 100% per core over Tahiti, Tahiti vs Tahiti scales about 50% per core.
Hawaii Has a different front end to Tahiti, it also renders twice the Triangles per Clock Cycle and has four times the ACE units vs Tahiti.
So who knows how good Tonga actually is, we will see soon enough.

Well that is very true.
The only thing I would say is have you ever known a corporate slide not to show the card in a favourable light. They have put the 285 up against the 760, because that is the card it will beat, if it was by 15% across the board then they would have pitted it against the 770 in the first place.
AMD have launched a new card (285) with another to follow very soon (285x) that have very similar performance to the out going 280 and 280x, which in itself is fine I suppose but the competition is about to move forward, raising the performance of each card up a notch (860=770, 870=780, 880=780ti, {I still reckon they will be faster than that but trying to be conservative here})
It just seems a really daft move to counter the competitions faster performance with cards that perform the same as the outgoing cards.
But as you say we will have to wait and see.

I edited the post, and added the ligitreviews link (for the third time now) so that you can actually check what the GTX 760, GTX 770 and R9 280X score, AMD's slide is right on.
Unless your saying AMD exaggerated their 285 scores? independent reviews will soon say 'if or not'.

285 is a great card, but 280/280X are also exceptional performers, bear in mind 280 is a 7950 and 280X is a 7970 so they are great performers.
But 280 is EOL and 280X soon shall be, so expect a 285X in the future.
We are hoping their shall be 4GB varients of the 285 and 285X as well, would certainly make sense considering how many 4GB 760 and 4GB 770 we sell.
I am not suggesting anything of the sort, I am just saying that they have pitted the card against the 760.
As for the 3d mark scores, I will let this nice chap explain just how nonhelpful those scores are.
I don't understand why reviewers measure a GPU's performance only to the overall (+CPU) score, its almost useless to measure a GPU's performance when you add in the infinite variation of the CPU.
Why don't they just use the actual GPU score????????? is it just me or is that too much like common sense?
Its clearly significantly faster than a GTX 760, but how it compares to the 280 it replaces is impossible to know as you would have to disentangle it from the CPU score they included.
Its so simple.
This is the combined score, this includes my CPU.
Score: 25600. it says nothing about how the GPU performs.
This is my GPU score, this is the bit that tells you how fast the GPU is, the GPU alone.
Graphics Score: 42177.
That ^^^^^ not the first, is the measurement that should be used to measure the GPU's performance.
Simple.

They won't be anywhere near £100
Probably won't sell for the full RRP, I hope, so I guess somewhere between £180 and £200. The RRP is $249 which is about £200 when you add sales tax.As Gibbo seems to be saying, the only reason to buy these is when there are no more 280s and 280X on the market
Some good deals in the MM, just snapped up a 280X myself.As a Red/Green neutral, I really hope nV can deliver something more exciting.

Your not getting it!!!!
AMD tested on a 6 core i7, a 3960X, ligitreviews tested on a 4960X, they both came to similar GTX 760 P Scores.
So with both on similar platforms scoring similar scores on the same GPU AMD were able to get P5650 on the GTX 760 with Ligitreviews P5570 also on a GTX 760 (a difference of 1.5%) Ligitreviews got P7070 on a GTX 770 and AMD P7066 on a 285.
So, with a bit of sourcing and maths you can see that the 285 is very close to the GTX 770, with in a couple of % give or take.

Oh I see. so the 3Dmark score are useless right up until someone from the green team uses them, then they are the most accurate thing out there 
You do realise that the 760, 670.680,770,7950,7970,7970GHz,280,280x (285,285x) are all with a few percent of each other anyway. That is the nature of this still stuck on 28nm for the last few years rut that we are in.

It's a shame the Tahiti cards are going eol, they've had some life span
I just find it odd they're replacing them with cards around the same speed but with a smaller bus, the wider bus on the 7900/280(x) is what made them pull away from the competition.
As for nvidia, well, they're rumoured to be going down the cheap 256 2/4gb road again so potentially nothing exciting, wish this die shrink would hurry up and hit the market, we haven't seen a decent performance jump in over 18 months.

The manufacturing process and to gain big leaps in performance is very hard now. 290X 8GB and Titan Black 6GB are and were incredible cards. Such performance from a single GPU is unlikely to be eclipsed.
780Ti 6GB would be an awesome part but won't happen, it shall be interesting to see memory configuration on 880/980 depending on what the desktop part finally ends up being called. But ideally we need 6GB cards on the high-end, even 8GB. Now 4k is really catching on and monitor technologies are improving quite quickly.

We're really waiting on the die shrink before the next jump in performance.
Which is somewhat strange, suddenly we've got massive movements in monitors, with very affordable 4K screens, and we're getting higher res 21:9 screens, so the requirement to drive them has gone up massively.
But for GPU grunt is pretty stagnant, it's actually a ridiculous scenario to be in.

Or you could just be over-thinking it and the reason why they pit the 285 against the GTX760 is because of the simple reason that it is the Nvidia card that's currently on the market at the same price point?
