Interesting.. This is running on the GK104 architecture right? The same architecture that was suggested to be running the GTX '640/660/660Ti/670' while GK110 was meant for the GTX 680 and 690.

Will be interesting to see if the GTX 690 will now be a single GPU card utilising all the extra power of GK110 with them possibly going back to a 690 GX2 type branding for the dual GPU variant.

If this all stacks up though and provided 3x the cores equals 2-3x the rendering performance then the GTX 680 will not only be a beast in relation to the GTX 580, but in relation to AMD's latest flagship HD 7970 also. Provided they price it sensibly and the benchmarks prove my suspicions then it's major bad news for AMD..

Looking forward to some more info on the 600 series of cards!

Am I the only one who sees how this is physically impossible? Do you know how massive the die size would have to be even with the new 28nm process? 6xx mm^2 pushing near 700mm^2. They think they had yield problems with fermi dies let alone what would happen with this monster.

This is assuming they haven't changed the shaders much. If they revamped the shaders then it's possible if the shaders are smaller than the previous gen.

Even if they cut out everything but the cuda cores it would be difficult to have 3x the shaders.

The GK110 may be 1536 shaders in the future but the cards that they release shortly will not be. Assuming it's the old shaders possibly 1024 or thereabouts but definitely not 1536... Here's looking forward to the 20nm half node

The CUDA cores should have a design.

It's the term used for the shader clocks being 2x the base GPU clock.

That's quite the speedy memory clock.

ok, cheers! so how will this effect performance/benefits? is it just a more efficient way of running things? sorry in advance for all the questions, but it's good to know things!

It just means the shaders are locked at double the GPU clock speed, which in turn makes them faster than as if they were set at the same frequency.
