6970 specs

Bear in mind the 6970 has 4 shaders in a group not 5 like the 5870, in theory the fifth shader on 5870 was never used so, based on just shader numbers alone, that makes it ~20% faster.

Would you not say 2 x downclocked 6970 cores with the 5970 being 2 x downclocked 5870 cores?

if this is true expect really exspensive limited edition cards with all 1600 shaders enabled

jees man where have you been over 3000 posts aswell tut tut lol
Are you saying the 6970 is twice the speed of 6850?
If so, show me them benchmarks!!

when is the 580 and 6970/90 due to be released?
The gtx580 is released tomorrow and the 6870 some time around the 22nd but if the rumours are true about manufacturing problems then who knows how late it could be. It would be pretty careless of amd to get things wrong on 40nm after handling all the problems so well in the first place. The only excuse they can have is they are bringing a new architecture to the game but still would be pretty shocking unless they have went for something around the same size as a fermi chip.

Again, the rumours are from two cards, one is 860, one is 890Mhz, one has 1536 shaders IF a program that doesn't know what card it is can read the shader count correctly. We know for a fact that AMD has a habit of sending out various cards with various shader/core speed combinations so it can track down leaks, meaning, if the 1536 shaders is accurate we both, don't know if it will have another cluster, or 4 in a "real" card, or not.
Likewise we don't know performance per shader, so its worthless speculating.
The Evergreen architecture definately DOES use the 5th shader, but not particularly often, in some situations it will basically have 20% more shaders, and in others when it does need to do a transcendental computation(what the 5th shader does) it will do it slower than the 5870 can do them. The general theory is they are uncommon enough that it should result in between 15 and 20% performance bump depending on the game, heavy use will mean 15% bump, barely any in the game and you'd get most of the 20% bump.
Then you've got, well the 6870 is a tweaked 5870 front end, which gave a huge performance boost per shader, the 6970 should have a new front end, theoretically you'd assume that AMD would have made it better, but it could potentially be not as good aswell.
A say 1920 shader 5870 with the 6870 front end tweaks would have been hugely faster than a 5870, if 1536 4 way shaders can perform like 1920 shaders, which is a 20% boost, then it could still quite easily beat a 580GTX.
Basically we have no idea, theres potential for 20% per shader performance increase, which would make 1536 equal to around 1880 Evergreen shaders, and a new front end that SHOULD be better than the 6870 front end, which provided a 35% efficiency in feeding the shaders/using the shaders. I'd be shocked if it was less than 35% faster, I'd be surprised if it was more than 55% faster, anywhere inbetween and at worst its going to be a great match price/performance for a 580GTX, at best, it can beat it, has better scaling, will be cheaper and an Antilles will be awesome value if it matches scaling of the 6870/50.
The biggest question for me is, 580GTX's size, and how many Nvidia can actually get out long term.
One last thing Raven, while Nvidia has a history of spoiling AMD launches with leaks and fake launches, AMD doesn't, AMD = as secretive as possible till the day of launch, thats how AMD rolls with GPU's and has done for some time.

Amd may come up with another 4 series launch every leak was suggesting a much lower shader count than the 4 series came with. The last 2 launches though have been pretty accurate with 5 and 6 series.

If there is a delay to the 69xx series - and its a big IF (fudzilla can't be believed to be impartial when it comes to graphics - putting a little FUD about is what its all about) - then its most likely to allow them tweak the default clocks in the BIOS to close/increase the gap (depening on which side of the 580 performance it comes out at at present) to/over the 580.
Its like F1 qualifying - once you know what the opposition have done, you have a target and the last one over the line wins (or should do).

Dual GPU cards scare me - They will never be in your system long enough to justify the initial price because you can guarantee that they will be obsolete by that time - new versions of DX that it doesn't support, newer architecture etc etc
I still have a 4870x2 which i bought at launch for £375 back in august 2008. It is obviously not as quick as some of the new cards but I think it represented good value for money.

Day old, not sure if it adds anything we dont already know:

Lets hope 6870 is slower than GTX 580. That will force ATI into releasing a "budget" performance card that almost matches 580 power, rather than another "expensive" performance card with similar of greater power.
90% of GTX 580 performance for sub £300 will be nice to see. The 6970 will of course beat GTX 580 by a fair margin, but it will also ~£500 at launch making it unrealistic for most people.
