The OpenGL version looks really aggressively bump mapped. The Cycle's version doesn't appear to have any bump mapping enabled.

Edit: The depth of field in the Cycle's version also looks a bit weird, and blurs away most of the terrain's detail.

The OpenGL version is using parallax mapping, where the pixels of the flat plane are rendered by ray-marching into a depth map:

The cycles version, on the other hand, is actually using the depth map to displace a high-res mesh -- a more general technique that should yield results as good or better than parallax mapping. I'd chalk up any perceived differences to lighting and material parameters.
