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 590 EVGA Classified Hydro Copper Edition.

The GTX 660 Ti has a 402 MHz higher core clock speed and 96 more Texture Mapping Units than the GTX 590. This results in the GTX 660 Ti providing 150.6 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 402 MHz higher core clock speed than the GTX 590, but the GTX 590 has 48 more Render Output Units than the GTX 660 Ti. As a result, the GTX 590 exhibits a 11 GPixel/s better Pixel Fill Rate than the GTX 660 Ti. 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 over a year more recently than the GTX 590, and so the GTX 660 Ti is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 590.

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 1024 MB more video memory than the GTX 590, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GTX 590 has 43.4 GB/sec greater memory bandwidth than the GTX 660 Ti, which means that the memory performance of the GTX 590 is noticeably better than the GTX 660 Ti.

The GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI has 2688 Shader Processing Units and the GeForce GTX 590 EVGA Classified Hydro Copper Edition has 1024. However, the actual shader performance of the GTX 660 Ti is 2984 and the actual shader performance of the GTX 590 is 1290. The GTX 660 Ti having 1694 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 Ti delivers a significantly smoother and more efficient experience when processing graphical data than the GTX 590.

The GTX 660 Ti transistor size technology is 12 nm (nanometers) smaller than the GTX 590. This means that the GTX 660 Ti is expected to run slightly cooler and achieve higher clock frequencies than the GTX 590.

The GeForce GTX 660 Ti Gigabyte WindForce 2X OC 2GB Edition SLI requires 300 Watts to run and the GeForce GTX 590 EVGA Classified Hydro Copper Edition requires 365 Watts. We would recommend a PSU with at least 600 Watts for the GTX 660 Ti and a PSU with at least 700 Watts for the GTX 590. The GTX 590 requires 65 Watts more than the GTX 660 Ti to run. The difference is significant enough that the GTX 590 may have an adverse affect on your yearly electricity bills in comparison to the GTX 660 Ti.
