In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI are significantly better than the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition.

The R9 270X has a 68 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 144 more Texture Mapping Units than the R9 270X. As a result, the GTX 660 Ti exhibits a 143.2 GTexel/s better Texture Fill Rate than the R9 270X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R9 270X has a 68 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 16 more Render Output Units than the R9 270X. As a result, the GTX 660 Ti exhibits a 14.3 GPixel/s better Pixel Fill Rate than the R9 270X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 270X was released over a year more recently than the GTX 660 Ti, and so the R9 270X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 660 Ti.

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 R9 270X, 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 96.4 GB/sec greater memory bandwidth than the R9 270X, which means that the memory performance of the GTX 660 Ti is massively better than the R9 270X.

The GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI has 2688 Shader Processing Units and the Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280. However, the actual shader performance of the GTX 660 Ti is 2984 and the actual shader performance of the R9 270X is 1251. The GTX 660 Ti having 1733 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 R9 270X.

The GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI requires 300 Watts to run and the Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts. We would recommend a PSU with at least 600 Watts for the GTX 660 Ti and a PSU with at least 500 Watts for the R9 270X. The GTX 660 Ti requires 120 Watts more than the R9 270X to run. The difference is significant enough that the GTX 660 Ti may have an adverse affect on your yearly electricity bills in comparison to the R9 270X.

Architecture & Other Relevant Data
For more information about the Architecture and Other Relevant Data, please refer to the Page of [GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition](http://www.game-debate.com/hardware/index.php?gid=1094&graphics=GeForce%20GTX%20660%20Ti%20WindForce%202X%20OC%20Edition).

Performance
Benchmarks Indicate a 6% Performance Boost over the Reference GeForce GTX 660 Ti in SLI.

System Suggestions
GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI is best suited for resolutions up to and including 2560x1440. We recommend a High-End Processor and 8GB of RAM for Optimal Performance.
Radeon R9 270X Sapphire Toxic 2GB OC Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling system called "Tri-X", which reduces the card's temperature under load, significantly and comes overclocked out of the box in the central unit that was increased from 1000MHz to 1100MHz, while the Boost clock is now of 1150MHz. Also, the operating memory clock is now of 1500MHz.
Benchmarks indicate a 5% performance boost over the standard edition and so this card will surpass a Radeon HD 7950.
