Total Performance Rating
The TPR graph is a combination of all our benchmarks in which NVIDIA and ATI are on an even playing field.
The TPR number is a combination of:
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.
All of the benchmark results achieved are then combined into a single number. As this graph will grow over time and cards won't be re-tested, next to each model you'll find the driver version that was used when the card was benchmarked.
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.
