There have been several rumors for a while now that NVIDIA would be building an LE version of the GeForce GTX Titan. We can now expand that even further, as it seems there will be two new models release. An even faster Ultra edition and thus the cheaper LE edition. German website 3dcenter claims that the GeForce GTX TITAN LE has 2496 Shader cores, 208 TMUs, 40 ROPs, and a 320-bit wide memory interface (5120 MB memory.) The tertiary GK110 product would then be the GeForce  GTX TITAN Ultra.

The Ultra would be a small upgrade for the 'regular' Titan, opening up one disabled SMX cluster bringing 2880 Shader cores with 240 TMUs towards the Ultra.

There remains a lot of speculation of course, but this could mean the Titan LE at  599 USD. The Original Titan at 799 USD, and the GeForce Titan Ultra at 999 USD.
