Total Performance Rating
The TPR graph is a combination of all our benchmarks in which NVIDIA and AMD are on an even playing field.
The TPR number is a combination of:
3DMark 11, Heaven Benchmark V2, Resident Evil 5, Tom Clancy's H.A.W.X.2, Mafia 2 (PhysX Off), Lost Planet 2, Aliens vs. Predator, 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.
Overall we've got some great performance from the setup which shows it very similar to the 2GB version. It's probably a little faster thanks to the more recent driver, but really, there's not much difference between the 2GB and 1GB models except the price.
