Overclocking, Performance Summary and Conclusion



Overclocking the Sapphire Radeon HD 3870 Toxic 512MB
Not worth the effort

To see what kind of extra headroom the Sapphire Radeon HD 3870 Toxic 512MB had hiding under the hood, we used the Overdrive control panel built into ATI's drivers.  In the end, Overdrive topped out at a GPU speed of 875MHz and Memory speed of 1342MHz (2684MHz DDR).  Unfortunately, the GPU speed was too high, with Half-Life 2:  Episode Two pausing and starting throughout the test.  With trial and error, we found the card to stabilize at a GPU speed of 850MHz, while the memory speed needed no further adjustment.
 



While the increase in GPU speed equated to a 6.25% boost, we recorded a 6.5% increase in frame rates at 1600x1200 while 1280x1024 jumped 7.25%.

Performance Summary:  In all tests, the Sapphire Radeon HD 3870 Toxic 512MB graphics card performed well and on a competitive level to that of the GeForce 8800GTX. When you consider the 8800GTX we used costs double that of the Sapphire Radeon HD 3870 Toxic 512MB, the Sapphire card really begins to show its value at the resolutions tested.
