In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Gigabyte OC 3GB Edition are significantly better than the Nvidia GeForce GTX 750 EVGA Superclocked 1GB Edition.

The GTX 750 has a 182 MHz higher core clock speed than the GTX 660, but the GTX 660 has 48 more Texture Mapping Units than the GTX 750. As a result, the GTX 660 exhibits a 43.7 GTexel/s better Texture Fill Rate than the GTX 750. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 750 has a 182 MHz higher core clock speed than the GTX 660, but the GTX 660 has 8 more Render Output Units than the GTX 750. As a result, the GTX 660 exhibits a 5.4 GPixel/s better Pixel Fill Rate than the GTX 750. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 750 was released over a year more recently than the GTX 660, and so the GTX 750 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 660.

The GTX 660 has 2048 MB more video memory than the GTX 750, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 also has superior memory performance overall.

The GTX 660 has 64 GB/sec greater memory bandwidth than the GTX 750, which means that the memory performance of the GTX 660 is much better than the GTX 750.

The GeForce GTX 660 Gigabyte OC 3GB Edition has 960 Shader Processing Units and the GeForce GTX 750 EVGA Superclocked 1GB Edition has 512. However, the actual shader performance of the GTX 660 is 1054 and the actual shader performance of the GTX 750 is 894. The GTX 660 having 160 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 750.

The GeForce GTX 660 Gigabyte OC 3GB Edition requires 140 Watts to run and the GeForce GTX 750 EVGA Superclocked 1GB Edition requires 55 Watts. We would recommend a PSU with at least 500 Watts for the GTX 660 and a PSU with at least 300 Watts for the GTX 750. The GTX 660 requires 85 Watts more than the GTX 750 to run. The difference is significant enough that the GTX 660 may have an adverse affect on your yearly electricity bills in comparison to the GTX 750.

GPU Mini Review

Mini ReviewGeForce GTX 660 Gigabyte OC 3GB Edition a special edition of GeForce GTX 660.
The new features include the WINDFORCE 2X 100mm Fansink equipped with "Triangle Cool" Technology solution which is more effective than the standard/reference cooler.
In terms of overclocking, the base-clock was increased from 980MHz to 1033MHz and the boost clock can now reach 1098MHz, instead of 1033MHz. The memory clock was left untouched.
Furthermore, the frame buffer was increased to 3GB though this will not boost its performance and can be addressed as a gimmick - marketing to lure consumers into paying more for the same product.
The overclocking is therefore significant and the performance boost is around 6% when compared to the standard GeForce GTX 660.
GeForce GTX 750 EVGA Superclocked 1GB Edition is a special edition of the fast-middle-class GeForce GTX 750.
This edition comes with a custom cooling cooling solution which by itself will allow a slight performance boost, as GeForce GTX 750 benefits from the GPU Boost 2.0 technology.
Furthermore, it comes overclocked out of the box in the central unit that was raised from 1020MHz to 1215MHz, while the Turbo Boost is now of 1294MHz, instead of 1085MHz. The operating memory clock was left untouched.
Further overclocking can be achieved easily, as the GPU has great OC potential.
Benchmarks indicate its performance is around 6% better than the reference card.
