Sapphire HD 4770 Review

,    -   
» Discuss this article (6)


To test out this new video card from Sapphire, I will run it through a series of game tests and synthetic benchmarks to see just how the performance compares to that delivered by similar video cards, as well as its direct competition from the green camp; nVidia. The OverclockersClub test system will be run as listed, with the processor operating at 3.0GHz. The respective video card settings that will be used are the driver defaults, with settings made in-game as noted to provide as few variables as possible. The only deviation from this method will be to disable Physx in 3DMark Vantage. I will only be testing from 1280x1024 up to 1920x1200, as any higher than this will result in a less than spectacular performance across the board.

Overclocked settings:

  • Sapphire HD 4770 830/850

Overclocking the HD 4770 involved so little drama that there really is not a lot to report, other than the fact I was limited to the clocks in the Catalyst Control Center because none of the popular software overclocking utilities are supporting the HD4770 yet. To get to the point, all it took to overclock the HD 4770 was to adjust the sliders to the maximum settings of 830/850, bump the fan speed to 85%, and let her rip. No fuss no muss overclocking. I can't help but think that ATI has been a bit conservative with the maximum clock speeds considering the GDDR5 memory on this card is rated for operation at 1000MHz. There is obviously some performance left on the table for the future.
