Recent rumor regarding the upcoming Titan LE and the Titan Ultra graphics cards has been updated and it appears that the Titan LE will actually be the GTX 780, marking the launch of the Geforce GTX 700 series lineup.
The Geforce GTX 780 will, of course, replace the GTX 680 and will be based on the same GK110 chip we saw on GTX Titan graphics cards. The new GTX 780 will end up to be slower than the GTX Titan, thus the Tital LE name, but should end up faster than the GHTX 680. According to the same report, Nvidia also plans the GTX 770 graphics card based on an improved GK104-425 28nm GPU. As you may remember, the GTX 680 was based on the GK104-400-A2 GPU so we might see some improvements with the new GPU.

According to early details, the GTX 770 should end up to be around 20 to 25 percent faster than the GTX 670 and it should be ready for launch in mid-May. The GTX 780 on the other hand is currently scheduled for the end of May or just before the Computex 2013 show kicks off in Taipai on 4th of June.

There were also some rumors regarding the GTX 760 Ti graphics card, a pretty much an updated GK104-225 GPU found in the current GTX 670 GPU. This one should put more pressure on AMD's mid-range lineup and should end up around 20 percent faster than the GTX 660 Ti.

Since these are practically rebrands and improved designs of the existing GPUs, the next-generation products are now shifted for GTX 800 series lineup and since Maxwell has been pushed to 2014, it looks like we'll wait for it a bit longer.
