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.
We can see when overclocked the GTX 570 GLH manages to leap from a few setups including the GTX 480 Lightning at 900MHz. It falls almost in line with the GTX 460 OC SLI setup and of course continues to just trail the much more expensive GTX 580.
