But when it come to dual cards, the 6950 has been shown to keep up and on occasion pass the sli 570 due the superior scaling.

I still don't understand why you're comparing cards that are in completely different price brackets.
Because in my country a 6950 costs as much as a 560 TI.
And a 570 costs 175$ more ...since you are so confident of the 6950´s superiority over the 570 I would like to ask you another question.
So considering the price they are very much unequal which is why I am so surprised about the by you clearified performance difference.


If unlocked to a 6970 the card simply gains 1536 Shaders Unified.
In that state is the card still able to be fully be overclocked like an actual 6970?
And still keep the card stable with reasonable temps?

If that was possible why does anyone even look at 570 & Co?
I think there is a catch somewhere...maybe the temps or instability...

What marketing strategy is behind this? why would AMD build a card which could be fully unlocked to the more expensive successor with absolutely no disadvantages of doing it?

First off the 570 is superior to the 6950, it supposed to be, hence the price premium.

When the 6950 competes it's at the dual card level.
When the 6950 sometimes wins, it's at the unlocked dual card level.

People choose the 570 because of the extras they may need, Cuda and physx.



As far as the oc ability, look around.

I would get users to post benchmarks for you for both GTX 570 SLI and 6950 CF, overclocked to the max on current drivers. Rememebr that many reviews will only have used drivers when the cards were released.

Personally dude. I would have got the GTX 480s for $240 each while the deal is still there, if shipping won't cost too much. It sounds like you are not in USA

6950 CF seems to be the most lucrative option right now.
Price is better than 570 SLI and the performance difference fluctuates.

Lack of Physx is frustrating but not devistating.
The 560 TI loses terribly against the 6950 CF.

http://www.youtube.com/watch?v=yESeP_27cqo

The unlock ability of the 6950 also makes it the king in SLI I think... don´t you?
6970 CF for the price of 6950 with just a simple bios flash lol?
That is not possible with the 570.
http://www.youtube.com/watch?v=Llshk...ure=grec_index

So 6950 CF or 570 SLI?
You pretty much summed it up for yourself. The 6950 CF is the way to go. Paying that little extra for 570 is not worth it, it's also a downgrade in terms on VRAM if it matters to you.

Stock 6950 CF wins against stock 570 SLI quite a few times. Even if it didn't; the performance in CF is so close to 570 SLI that the 570 price isn't justified.

To answer your Q in the other thread OP:

It is a kinda Windows/Apple deal here^^.

I actually did not know that the 6950´s were so great?
I have never heard about them but you guys have awakened my interest in them.
They cost just as much as the 560´s and yet they deliver the same performance as a 570 SLI setup ..hmmm where is the catch??

What overclocks best? 6590 CF? 570 SLI? 560 SLI?

Also more and more games are using Physx now ...don´t you think that will have an affect on the AMD cards?
There's no catch really. You should rule out the 560 as it doesn't stand a chance even though it's a good overclocker. 570 can be decent overclockers if you get a good sample, but that isn't guaranteed and you risk killing your card by overvolting. 6950 overclocks decently. Personally I don't think PhysX will ever be that good and there's still not many games utilizing it, definitely not the deciding factor.

So let´s sum it up again.

An AMD 6950 has the ability to be unlocked to a full AMD 6970 without any disadvantages or flaws coming with that upgrade.
That means architecturewise and performancewise it will be completely equal to a full AMD 6970.

Also overclocking and stability will not be affected in any negative way by this upgrade and will behave just like they would with a normal AMD 6970.

That should work with any AMD 6950 regardless if it is reference or non reference design.

Personally I do not understand this would even be made possible by AMD because there is no marketing gain behind it whatsoever but ok^^.

That being said the comparison has changed from 6950 CF vs 570 SLI to

6970 CF(unlocked 6950´s) vs 570 SLI ....performancewise the 6950´s will win by a landslide.

Also the superior VRAM will aid at higher resolutions and AA etc settings.

The only downfall would be Physx and CUDA ...but now I believe that until Kepler there won´t be games out that would benefit from both technologies that much to be a decisive factor over wheter or not to get 6950 CF or 570 SLI.

So lol ....better price , better performance, unlock ability which grants the performance level of the successor card which costs more with not disadvantages or flaws whatsoever,Eyefinity etc etc ....

Bruce Mod you were right it wasn´t even a competition from the start lol?
I really do not understand why people aren´t all over this card ?^^

But I would like to stress one factor a little more :
Is there really no documented disadvantage in the unlocking of a 6950 to a 6970?oO
Same overclocking ability, same performance level, same heat and stability?
So absolutely no downfall in any way from this??

2x6970 = 6990(fastest card in the world) that means for the price of 2x6950 which is roughly 39% less than an actual 6990 I could still get equal or even better performance?

Some GTX 465s Unlocked to 470s and were way cheaper but they didn't actually overclock as far as a real GTX 470. I would expect the same for a 6950. If they do unlock though, at least you are guranteed 6970 speeds

Unlocked 6950s won't be as good as 6970s. They are still not the same card physically. Unlocking the shaders is pretty much risk free, flashing the card's BIOS to a 6970 however, is not risk free, but that's what you have the dual BIOS switch for.

Powercolor PCS+ comes with the unlocked 6970 BIOS allready installed and 6950 Twin Frozr III is said to flashable

Otherwise you have to buy reference if you want 6950 flashed to 6970.

The performance difference between flashing to 6970 and unlocking a 6950 and then overclocking the core and memory to near the 6970 standards is a bit safer and brings them to almost negligible performance difference. Take your pick really.

Flashing/unlocking the 6950 is overrated. Most of the performance difference between the 6950 and the 6970 is clock speed, therefore overclocking yields a larger performance increase than unlocking. You will gain 1-3% in performance from unlocking where as you will gain 10-15% (6970 performance and beyond) from overclocking. See the comparison in my signature.

The 6970 gives you the performance without the hassle and as a result carries a premium price over the 6950. The 6970 has better rated memory for a potential higher memory overclock. Also, the chips binned for 6970 have potential for a higher core overclock as well.

But according to you except a few non ref cards only the reference 6950 are able to be flashed to a full 6970 not only the shader.

You say that the 6950 is not equal to the 6970 in its structure.
Look here: 00:34

http://www.youtube.com/watch?v=zvp5-...mbedded#at=192

He clearly states that it was impossible for a 570 to be unlocked to a 580 because of its fewer functional units ...unlike with the 6950 which only has software limitations distincting it from a 6970.

So the 6950 should be able to fully be unlocked (Bios flash , shader) and therefor fully equal a 6970 in its performance,overclock ability, etc etc sine the structure and architecture desing is completely the same.

Still I would like this to be confirmed once more.
Also the fact that the unlocking is only possible with the reference cards and some of the non ref´s and not every 5950 and of course why this is the case.

The 6970 gives you the performance without the hassle and as a result carries a premium price over the 6950. The 6970 has better rated memory for a potential higher memory overclock. Also, the chips binned for 6970 have potential for a higher core overclock as well.
You are talking like as if we had to choose wheter to unlock the 6950 or to overclock.

I am talking about fully unlocking it and then overclocking the card like a normal 6970 to the maximum.
