3DMark06 Benchmark Results

3DMark is a computer benchmark by Futuremark (formerly named Mad Onion) to determine the DirectX 9 performance of 3D game performance with graphics cards. 3DMark06 uses advanced real-time 3D game workloads to measure PC performance using a suite of DirectX 9 3D graphics tests, CPU tests, and 3D feature tests.

3DMark06 tests include all new HDR/SM3.0 graphics tests, SM2.0 graphics tests, AI and physics driven single and multiple cores or processor CPU tests and a collection of comprehensive feature tests to reliably measure next generation gaming performance today. Some enthusiasts may note that Benchmark Reviews does not include CPU-bound tests in our benchmark battery, and that only graphic-bound tests are included.

Here at Benchmark Reviews, we believe that synthetic benchmark tools are just as valuable as video games, but only so long as you're comparing apples to apples. Since the same test is applied in the same controlled method with each test run, I believe 3DMark is a very reliable tool for comparing graphic cards against one-another.

More visitors to Benchmark Reviews operate at 1280x1024 resolution than any other, as it represents the native resolution of 19" LCD monitors. Using this resolution as a starting point, the maximum settings were applied to 3dMark06 which for these tests include 8x Anti-Aliasing and 16x Anisotropic Filtering. Low-resolution testing allows the graphics processor to plateau maximum output performance, which thereby shifts demand onto the system components to keep up. At the lower resolutions 3DMark will reflect the GPU's top-end speed in the composite score, indicating full-throttle performance with little load. This makes for a less GPU-dependant test environment, and is helpful in measuring the maximum output performance in the test results.

To start things off, I ran the ASUS EAH4870 DK Top at the default 3DMark06 settings. This establishes a baseline that we can use to analyze the effects of increased resolutions and post processing. It also allows these scores to be compared in Futuremark's online results browser. As expected, the ASUS 4870 has a clear performance lead over its siblings, scoring up to 32% higher than a stock HD 4850.

With anti-aliasing and anisotropic filtering enabled, scores drop considerably across all of the test cards. However, the increased bandwidth of the EAH4870's GDDR5 memory and higher clock speed keep it well above the HD 4850.

After increasing the test resolution, scores drop again, but this time not as drastically. At this point, the EAH4870 expands its lead over the HD 4850, offering a performance increase of 35%.

Our final 3DMark06 test represents the worst case scenario for most gamers. Resolution, anti-aliasing, and anisotropic filtering are maxed out, taxing the video card more than most games ever would. At these settings, the EAH4870 is in a league of its own, leading the HD 4850 by as much as 45%.
