GK110 and GK104
Nvidia is about to launch desktop Geforce GTX 700 series cards and this time the launch starts from the top down. The GTX 780 is set to replace the GTX 680 and the new card is based on the GK110 chip that we all know from Titan cards.
The chip is actually slower than Titan and is internally called Titan LE, which means that GTX 780 should end up slower than Titan cards. Our sources claim that the card should end up about 30 present faster than the GTX 680 and the launch date is expected by the end of May. This means the card comes very close to Computex, the biggest computer trade show in Asia that kicks off on June 4th.
The runner up is continuing the naming tradition and is simply named Geforce GTX 770. It is based on a new GK104 – 425 improved 28nm core. The current GTX 680 has the GK104-400-A2 core, and the 425 implies some slight optimisation and changes.
The GTX 770 stays loyal to the Kepler architecture and just like with the GTX 680, we can expect one cluster less compared to GTX 670. Performance wise the card should be between 20 and 25 percept faster than the GTX 670. The launch is expected in mid May.
The real next generation has now been shifted to Geforce GTX 800 series, in case Nvidia continues the same naming tradition and it is going to be based on Maxwell. This new GPU promises a huge leap forward with capability of more than twice the Giga Flops per watt than Kepler. Maxwell has been pushed to 2014, but we don't know the exact date.
Geforce GTX 780, 770 coming in May
Visiting Asia has its treats. From a foot massage in Hong Kong to a 55" 4K panel in Shenzhen for $1600, it's easy to find what are you interested in. It is also easy to listen to the beat of the street. One such find are three new Nvidia boards coming in the next couple of weeks, boards that will push to fill all the gaps in the product stack.
First and foremost, few weeks back, several websites leaked the news about a part called GeForce GTX Titan LE, a board based on cut down GK110 GPU silicon. The leak was right, since this will actually be a consumer version of Tesla K20C, the 2496-core part with 5GB of GDDR5 memory. The name will not be the GTX Titan LE, though. Meet the GeForce GTX 780 5GB. Just as the GTX Titan was a consumer version of the K20X (2688-core part, 6GB GDDR5 memory), K20A/C is getting a consumer version as well. The performance is about 30% faster than a single GTX 680. You can expect this board to launch (hard launch, availability from Day 0) in the final days of May, as the Computex train starts to heat up. Pricing unknown, but you should prices anywhere between $499 and $599.
Second board will be the GeForce GTX 770. This is actually based off a GK104-425 die e.g. nothing more than a higher clocked GTX 680. Estimated performance is 20-25% better than GTX 670, on pair with the regular GTX 680. This is still a 256-bit interface part, with 4GB GDDR5 memory to be more prominently featured than a 2GB one. Nvidia's product stack calls for 6GB Titan, 5GB GTX 780, 4GB GTX 770 and 2GB GTX 760 Ti. Launch is allegedly scheduled for mid-May, as a precursor to the GTX 780.
Which brings us to the third product, the GeForce GTX 760 Titanium. GTX 760 Ti, sorry. This part is based on the same die as GTX 670; GK104-225. The board comes with 2GB GDDR5 memory and will do everything to put pressure on AMD's HD 7800 and 8800 line of OEM cards. Performance is targeting 20-23% increase from the standard GTX 660 Ti, and this is the part that will launch at the 2013 Computex Taipei trade show.
Naturally, there's a possibility that Nvidia will launch all three parts together and claim the best product stack for gamers out there.
Until Maxwell (GMxxx) arrives in 2014, do not expect new silicon from Nvidia. Come to think, AMD is also holding back its Volcanic Islands (VI) for the tail end of 2013 or in 2014. Next-gen processes cannot come soon enough for these companies... and yes, FinFET transistor on a 10-figure transistor count is a big challenge.

Now this news has put a big smile on my face.
