In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti SLI are significantly better than the AMD Radeon HD 7870 DirectCU II 2GB Edition.

The HD 7870 has a 95 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 144 more Texture Mapping Units than the HD 7870. As a result, the GTX 660 Ti exhibits a 124.2 GTexel/s better Texture Fill Rate than the HD 7870. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7870 has a 95 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 16 more Render Output Units than the HD 7870. As a result, the GTX 660 Ti exhibits a 11.6 GPixel/s better Pixel Fill Rate than the HD 7870. 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 HD 7870, 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 HD 7870, 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 133.5 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the GTX 660 Ti is massively better than the HD 7870.

The GeForce GTX 660 Ti SLI has 2688 Shader Processing Units and the Radeon HD 7870 DirectCU II 2GB Edition has 1280. However, the actual shader performance of the GTX 660 Ti is 2634 and the actual shader performance of the HD 7870 is 1099. The GTX 660 Ti having 1535 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 HD 7870.

The GeForce GTX 660 Ti SLI requires 300 Watts to run but there is no entry for the Radeon HD 7870 DirectCU II 2GB Edition.

GPU Mini Review

Mini ReviewGeForce GTX 660 Ti SLI is a solution of two GeForce GTX 660 Ti put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 660 Ti to know more about its chip.
As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to X% better than a single GeForce GTX 660 Ti performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 660 Ti. Expect this combination to draw up to 300 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
Radeon HD 7870 DirectCU II 2GB Edition is a special edition of the powerful Radeon HD 7870. See the standard version for more information about it.
The new features include the DirectCU II cooling solution which is 20% more effective than the reference cooler, according to Asus and a small increase in the core-clock to 1010MHz as well as in the memory clock to 1210MHz.
Benchmarks indicate almost no performance boost when compared to the standard Radeon HD 7870 and so its performance is on level with the it as the boost is beneath 1%.
All games, including demanding one's, will run on the highest settings.
