A GTX 680, but more affordable.
For testing the new GTX 670, the below testbed was used.
Note: The other cards may not always match up to the performance of the one being tested due to new drivers. In this case I used GeForce 301.33 for testing the Zotac GTX 670 AMP! Edition.
Benchmarks & Settings
Below are the details of how each benchmark was conducted with specific details of settings used. All of the below benchmarks were run at a resolution of 1920×1080.
Overclocking the Nvidia reference GTX 670 was quite easy. I bumped the voltage in ASUS GPU Tweak fro 987mV to 1175mV, allowing me to bump speeds up to (boosted) 1105MHz. While this 13% increase in core clock speeds was impressive, in real life it didn’t yield any performance gain over 2%.
Similarly the Zotac GTX 670 AMP! Edition, no matter how much I pushed the voltage, would not go beyond 1245MHz. This 6% increase in core clock barely resulted in a performance increase beyond 1%. Therefore none of these results will be shown in the benchmarks below as they barely make a dent in the overall scheme of things.
