I was looking through NewEgg and saw that they have the 6800LE as having the same clock speed on the RAM and core as the standard 6800. Is this a typo or is their some other difference (pipelines etc)? Thanks.
The 6800LE has 8 Pixel Pipelines, and 4 Vertex Shaders, while the 6800NU has 12 Pixel Pipelines, and 5 Vertex Shaders. Both have a 256bit memory interface, thats about it.
Chances of them unlocking are amazingly rare. Those are not only the 6800U/GTs that didnt make it, but also the 6800nu's that didnt pass, so you can gather that chances of unlocking are extremely little.
