The TPR graph is a combination of all our benchmarks in which NVIDIA and ATI are on an even playing field.
3DMark Vantage, Heaven Benchmark V2, Resident Evil 5, Tom Clancy's H.A.W.X., Mafia 2 (PhysX Off), Lost Planet 2, Aliens vs. Predator, Final Fantasy XIV, Street Fighter IV, Far Cry 2, Batman: Arkham Asylum (PhysX Off) and our four High Quality tests which include Mafia 2, Aliens vs. Predator, Street Fighter IV and Far Cry 2.
What we see is with all the numbers together the card does fall a little behind the GTX 460 overall. That's mainly due to the higher number benchmarks like 3DMark Vantage and Final Fantasy XIV impacting overall performance a bit more. Of course, it has to be taken into account that the GTX 460 is overclocked quite high and the HD 6850 is at stock clocks.
