In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 SLI are noticeably better than the Nvidia GeForce GTX 670 DirectCU II OC Edition.

The GTX 670 and the GTX 660 have the same core clock speed of 980 MHz, but the GTX 660 has 48 more Texture Mapping Units than the GTX 670. As a result, the GTX 660 exhibits a 47 GTexel/s better Texture Fill Rate than the GTX 670. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 670 and the GTX 660 have the same core clock speed of 980 MHz, but the GTX 660 has 16 more Render Output Units than the GTX 670. As a result, the GTX 660 exhibits a 15.6 GPixel/s better Pixel Fill Rate than the GTX 670. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 660 was released less than a year after the GTX 670, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 660 has 2048 MB more video memory than the GTX 670, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 also has superior memory performance overall.

The GTX 660 has 96.1 GB/sec greater memory bandwidth than the GTX 670, which means that the memory performance of the GTX 660 is massively better than the GTX 670.

The GeForce GTX 670 DirectCU II OC Edition has 1344 Shader Processing Units and the GeForce GTX 660 SLI has 1920. However, the actual shader performance of the GTX 670 is 1422 and the actual shader performance of the GTX 660 is 1983. The GTX 660 having 561 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 670.

The GeForce GTX 660 SLI requires 280 Watts to run but there is no entry for the GTX 670. We would recommend a PSU with at least 600 Watts for the GTX 660, but we do not have a recommended PSU wattage for the GTX 670.

GPU Mini Review

Mini ReviewGeForce GTX 670 DirectCU II OC Edition is a Special Edition of the powerful GeForce GTX 670. See the standard version for more information about it.
The new features include an increase in the core-clock that went from 915MHz to 980MHz while the Turbo Boost is now of 1058MHz. A 20% more effective cooler is also included.
The performance boost is significant and around 5% when compared to the standard GTX 670.
Most demanding games will run at the highest settings.
GeForce GTX 660 SLI is a solution of two GeForce GTX 660 put together using NVIDIA'S SLI technology.
SLI relies a lot on proper driver support and may cause micro stuttering in FPS below 30. This means this combination might even perform worse than a single GTX 660.
The optimal performance it delivers is largely better than a single GeForce GTX 680.
Therefore, this combination is sufficient for gaming at 1080p and most demanding games can be played at the highest settings.
