Zotac customizes the GTX 680 with industrial design.
For testing the Zotac GTX 580 AMP! Edition the below testbed was used.
For comparison I have used the reference Nvidia GTX 680, the overclocked ASUS HD 7970DCUII and the overclocked Zotac GTX 580 AMP! Edition.
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 301.24 for testing the Zotac GTX 680 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.
I managed to overclock the Zotac GTX 680 AMP! Edition to 1236MHz. That’s a paltry 5% increase. Trying to fiddle around with the voltage and memory settings didn’t result in any success whatsoever; while Windows 7 was running just fine, most of the benchmarks were crashing. It’s sad, but not surprising. In all of our benchmarks this overclock resulted in virtually the same performance, with just 1 or 2 FPS increase.
That said, when running at factory speeds of 1176MHz, the Zotac GTX 680 AMP! Edition does boost up to 1201MHz; again a small, but worthwhile speed bump.
