Sapphire HD4830 512MB Review

» Discuss this article (0)


With the HD 4830 being based off of the HD 4800 series RV770 core I am quite excited on seeing what the Sapphire HD 4830 has install for us today. To gauge the scores on an average I will be including a slew of cards currently on the market so you can see where it stands among the mid to high range video cards. To eliminate any variables all hardware will be ran at stock speeds, timings, and voltage so there will be no interference in the numbers. All of the hardware will remain the same for each video card tested to keep the scores fair.

  • Sapphire HD 4830 670/995

To overclock the Sapphire 4830 card I went with the Catalyst Control Center Overdrive program which I knew worked with this new card. I started upping the GPU speed 5MHz at a time until the card became unstable. Then I backed it down little by little until I had a stable overclock on the GPU. Next I followed the same steps on the memory however I stated the overclock at 950MHz since i know the memory is rated for 1000MHz per the manufacturer. I almost hit that ceiling ending up at 995MHz (1990MHz Effective). This is where our overclocking numbers will be ran at.
