Gigabyte GTX 660 OC Video Card Review

Over the past few months we have gotten to see two great NVidia based video cards using the GTX 670 and GTX 660 Ti GPUs.  Based on those reviews we can see the power of the NVidia Kepler architecture and how it can make PC gaming fun again.  In some ways those two cards were very similar.  They both featured the same number of CUDA cores and similar overclocking headroom.  In fact the only major difference was the memory controller.

In this review we will be looking at the new video card from Gigabyte called the GV-660OC-2GD.  This is a GTX 660 [Non-Ti] based graphics card using the entirely new GK106 GPU.  

Graphics Processing Clusters 3
SMXs 5
CUDA Cores 960
Base Clock 1033 MHz
Boost Clock 1098 MHz
Memory Clock 6008 MHz
Total Video Memory 2GB GDDR5
Memory Interface 192-bit
Fabrication Process 28 nm
Thermal Design Power (TDP) 115 watts

There are a few key differences between the GTX 660 Ti and the GTX 660 including a less complex GPU in terms of total CUDA core count, a change in the SLI configuration and a lower overall TDP target.  GPU Boost is still active on the GTX 660 and typically scales with the base clock which is further enhanced (or reduced) by the power target slider.  

Gaming features are identical to other Kepler based GPUs including the popular Adaptive VSync, single card surround and game engine based TXAA.
