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

The GTX 660 Ti has a 39 MHz higher core clock speed and 112 more Texture Mapping Units than the GTX 670. This results in the GTX 660 Ti providing 118.5 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 660 Ti has a 39 MHz higher core clock speed and 16 more Render Output Units than the GTX 670. This results in the GTX 660 Ti providing 17.5 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 660 Ti 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 Ti 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 Ti also has superior memory performance overall.

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

The GeForce GTX 660 Ti Power OC Edition SLI has 2688 Shader Processing Units and the GeForce GTX 670 DirectCU II OC Edition has 1344. However, the actual shader performance of the GTX 660 Ti is 2949 and the actual shader performance of the GTX 670 is 1422. The GTX 660 Ti having 1527 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 Ti delivers a massively smoother and more efficient experience when processing graphical data than the GTX 670.

The GeForce GTX 660 Ti Power OC Edition SLI requires 300 Watts to run but there is no entry for the GeForce GTX 670 DirectCU II OC Edition. We would recommend a PSU with at least 650 Watts for the GTX 660 Ti.

GPU Mini Review

Mini ReviewThe SLI solution of GeForce GTX 660 Ti Power OC Edition.GeForce 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.
