It will be based on a cut-down version of the GK110 GPUOver the past month or so, there has been a low murmuring on the Internet that NVIDIA might release a GeForce 700 series graphics card, GTX 780 maybe, but new information suggests something altogether different.
The newer rumor is that a cheaper variant of the NVIDIA GeForce GTX Titan will make its appearance, one with a cut-down version of the GK110 graphics chip.
The software called HWiNFO revealed this, in a changelog that says it will support both the GK208 based mobile GPUs and the GK110 based GTX Titan LE.
The folks at SweClockers were the ones to spot the log, and they surmised that GTX Titan LE would be a cheaper and slower version of the original.
We suppose the LE stands for Limited Edition, though it would be a bizarre thing. The original GTX Titan was supposed to be, itself, a limited rum of around 1,000 units.
In any case, the modified GTX Titan LE would have 2,496 CUDA cores and a memory interface of 320 bits for the 5 GB of GDDR5 VRAM.
For the sake of comparison, the full one has 2,688 CUDA cores, 6 GB of memory and an interface of 384 bits.
Overall, the GTX Titan LE should perform somewhere between GTX Titan and the GTX 680 or maybe the GTX 690 dual-chip.
We will have to wait and see, though we aren't sure for how long. While we are pretty sure the launch won't happen later than the third quarter of the year (2013), there is no launch date anywhere.
