Benchmarks

FutureMark 3DMark03

FutureMark 3DMark05

AquaMark3

Doom 3 Timedemo Demo1

Battlefield 2 Custom Daqing Oilfield Flyby

Half Life 2: Lost Coast custom timedemo

3DMark03, 3DMark05, and AquaMark3 were run at default benchmark settings. In Doom 3 and Battlefield 2, the video cards were first benchmarked at a standard 1280x1024x32-bit using the highest graphics quality settings in game. Where noted, the second of scores shows the performance with 4x Anti-Aliasing, Anisotropic Filtering 16x, or both enabled. 

In Lost Coast, our custom timedemo was run with maximum settings including 4xAA and AF16, but with HDR on or off:

Overclocking and Unlocking:

To our dismay, Nvidia really has maxed out their core and memory this time, leaving little headroom for fun. Using the below Nvidia software utility, we were only able to overclock the video card to 581 MHz core / 1.75 GHz memory (Default 550/1700). Furthermore, we also experienced a software issue between the Nvidia and Rivatuner overclocking utilities and 3DMark because any change in clock speeds would cause the desktop to become distorted and garbled upon starting 3DMark. Due to these marginal overclocks and difficulties, we omitted overclocked benchmark results as they would not have shown any significant performance gain in the first place.

According to Rivatuner, all existing pipelines and vertex shaders were enabled:
