920mhz is not too bad. Its look a bit better.
Still needs more testing because Vanatage doesnt make use of any tesselation so power draw wont be much.
Nvidia's solution has tessellation computations performed by the stream processors ("CUDA cores"), rather than an external tessellator unit. So, a scene that uses tessellation won't necessarily stress the GPU any more than one that does not.
After all, we all know that furmark is the most intense stress test, and that certainly does not use any tessellation.
