Overclocking the Sapphire X1950 XTX

For our next set of performance metrics, we spent a little time overclocking the Sapphire Radeon X1950 XTX using the clock frequency slider available within ATI's Catalyst drivers, under the "Overdrive" tab.

(Fast 3D Video Card) + Overclocking = Even Faster Card

To find each card's peak core and memory frequencies, we slowly raised their respective sliders until we begun to see visual artifacts on-screen while running a game or benchmark, or until our test system was no longer stable.

When all was said and done, we were only able to push the Sapphire Radeon X1950 XTX's GPU core and memory clock speeds up by relative small margins. In its stock configuration, the card operates with a 650MHz GPU core and 1.0GHz (2GHz effective) GDD4 RAM. While overclocking the card, we were able to crank the GPU speed up to 695MHz and the memory up to 1080MHz (2.16GHz effective), increases of 45MHz and 80MHz, respectively.

With the Sapphire Radeon X1950 XTX overclocked, we re-ran a couple of high-resolution benchmarks - namely F.E.A.R. and Prey - to see what kind of performance we had gained. Ultimately, F.E.A.R's performance went up by 2 frames per second, and Prey's went up by 2.4 FPS. The small increase in F.E.A.R. performance was enough to match the performance of the GeForce 8800 GTS.
