In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI are noticeably better than the Nvidia GeForce GTX 770 Palit JetStream 2GB Edition.

The GTX 770 has a 118 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 96 more Texture Mapping Units than the GTX 770. As a result, the GTX 660 Ti exhibits a 84 GTexel/s better Texture Fill Rate than the GTX 770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 770 has a 118 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 16 more Render Output Units than the GTX 770. As a result, the GTX 660 Ti exhibits a 12.7 GPixel/s better Pixel Fill Rate than the GTX 770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 770 was released less than a year after the GTX 660 Ti, 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 770, 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 64.1 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the GTX 660 Ti is much better than the GTX 770.

The GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI has 2688 Shader Processing Units and the GeForce GTX 770 Palit JetStream 2GB Edition has 1536. However, the actual shader performance of the GTX 660 Ti is 2984 and the actual shader performance of the GTX 770 is 1846. The GTX 660 Ti having 1138 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 770.

The GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI requires 300 Watts to run but there is no entry for the GeForce GTX 770 Palit JetStream 2GB Edition. We would recommend a PSU with at least 600 Watts for the GTX 660 Ti and a PSU with at least 550 Watts for the GTX 770. The GTX 660 Ti has been recommended a PSU with 50 Watts more than the GTX 770. The difference is significant enough that the GTX 660 Ti may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 770.

GPU Mini Review

Mini ReviewGeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI is a Solution of two GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition put together using NVIDIA's SLI Technology.

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.
GeForce GTX 770 Palit JetStream 2GB Edition is a special edition of the high-end GeForce GTX 770.
This edition comes with a custom triple fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 770 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 1046MHz to 1150MHz while its boost clock is now of 1202MHz. The memory clock was left untouched.
Benchmarks indicate a 6% performance boost when compared to the reference card and so this edition performs very slightly better than GeForce GTX 590.
