Titan will be discontinued.

Is that a guess?

In any case, if the 3DMark scores you posted end up being true, this war for the fastest card will give us cards with Titan performance or higher for quite a bit less money.

We win!

Another sauce.

The rumors says 3GB reference but there will be 12GB variants.

+ The rumor has it that NVIDIA GTX 780 Ti will be available in 3 versions: 3GB, 6GB and even 12GB.
+ NVIDIA GTX 780 Ti features 876 MHz base clock and 928 MHz boost clock. I managed to confirm that with stock cooler it can overclock up to 1240 MHz (based on Afterburner readings). I even saw a GPU-Z screenshot with 1851 MHz memory clock (7.4 GHz). I don’t know if these are stable clocks, all I know it was enough to complete multiple 3Dmark benchmark runs, which I saw.
+ Long story short, the GTX 780 Ti is about 6% faster than R9 290X, this is out-of-the-box performance. With overclocking GTX 780 Ti can be 15-23% faster than R9 290X.

Cards with 6GB is a given knowing that several partners have been offering cards with twice the amount of RAM in the past (670, 680 and even 570 and 580 that I remember, specially EVGA) but why, in the name of whatever you believe in, will they go with is 12GB? It's ridiculous.

Yeah, I know "more memory is better at 4K", and yet the 4GB 290X beats the 6GB Titan at 4K, probably for the higher bandwidth so it's not all about more memory.

they leaked some benchmarks from actual games as well

"System power consumption is definitely higher than other cards. We are looking at 500 watts here, which is definitely more than R9 290X in this comparison. The leaker claims that the card is running at average 970 MHz, which is 50+ MHz overclock. The GTX 780 Ti is supposedly labeled with a maximum power draw at 275W, that’s without any clock manipulation. Rising the clock could led to rapid power increase. These numbers will require much more sophisticated review just to be sure."

"Gaming benchmarks revealed that overclocked GeForce GTX 780 Ti can compete with R9 290X in high resolution tests. In 1080p and 1600p, GTX 780 Ti clearly outperforms other cards in this comparison, but since it only uses 384-bit interface, the higher the resolution the worse the performance gets. In Battlefield 3, which is AMD Gaming Evolved title, overclocked GTX 780 Ti can offer much better performance in every resolution. However, let me remind you again, this is overclocked card that we are talking about.

The leaker claims that these tests were performed with unofficial drivers, performance can still get better when NVIDIA releases final version of its drivers."

My God. More power than a 290X?

We need 20nm asap.

Official benchs from nVidia.

Oh, those rascals (or is it rogue?) of Nvidia using the Quiet mode...

Mind you, I'm not saying that the 780Ti isn't faster than a 290X, just that they know how to make things look even better for them.

By the way, the 780Ti has more memory bandwidth than a 290X? Titan has 288 GB/s and the 290X has 320GB/s. 780Ti will have... 350GB/s?
