NVIDIA will reveal three new GeForce GTX 700 series branded cards in the coming weeks, likely around Computex time (end May / beginning of June). These cards will be based on current GPUs though, the next-gen architecture (aka Maxwell) from NVIDIA isn't expected to arrive until 2014, so we have to make due with slight updates of current offering.

The rumor comes from Bright Side of News, here's their skinny:

"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.
