Race Driver: GRID loves memory bandwidth, and the HD 4850 staves off the upstart at both resolutions.
Summary
Our benchmarks have shown the Radeon HD 4770 to be a surprisingly capable performer, laying down benchmark results that were on the high side of expectation. It's run with a press-driver rather than Catalyst 9.4 final, but performance is consistent enough to beat out Radeon HD 4830 and match HD 4850. It's also faster than the GeForce 9800 GT, by a significant amount in some cases, and doesn't lose a single benchmark to it.
Overclocking
Why no overclocking numbers in the review? At the time of testing the only application that could overclock the card was AMD's own OverDrive, which had a pitifully low range. We will update this section as soon as the card can be pushed to the limit.
