This should be the first independent test:

Thanx. Its a fine test, but is it MP or SP?
What is shows is imho medium and 1080p is to long a stretch for kaveri mantle or not.
I think there is a solid improvement where it mappers at the 1% worst situations. A 15-19% improvement here. The 720 mantle graph looks really, really smooth. I think personal subjective test is nessesary to assess the improvement. A good start for a beta, i could use that on my machine. lol.
