For our next set of performance metrics, we overclocked the Radeon X1650 Pro using ATI Tray Tools. Along with a manual option, this application can auto detect the highest stable GPU and Memory frequency by scanning for artifacts while slowly increasing the clock frequency. In the end, the peak GPU speed we could attain with our sample was 641MHz, an increase of 3.2%. The memory speed increased to 1450MHz DDR, 5.3% over the default clock speed. Next, we put these new gains to the test by re-running our custom Prey timedemo test again.
When comparing the overclocking results of the HIS X1650 Pro with its stock results, we registered a 6.27% increase at 1024x768. At 1280x1024, the gain increased to 11.52% while at 1600x1200, a boost of 4.5% was recorded. Across the board, the results were much closer to the GeForce 7600 GT but not enough to overtake it.
