In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 v2 are significantly better than the Nvidia GeForce GTX 750 Zotac 1GB Edition.

The GTX 750 has a 40 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 46.3 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 40 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 7.3 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 660 was released less than a year after the GTX 750, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 660 has 1024 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 64.2 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 v2 has 960 Shader Processing Units and the GeForce GTX 750 Zotac 1GB Edition has 512. However, the actual shader performance of the GTX 660 is 1016 and the actual shader performance of the GTX 750 is 768. The GTX 660 having 248 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 v2 requires 140 Watts to run and the GeForce GTX 750 Zotac 1GB Edition requires 55 Watts. We would recommend a PSU with at least 450 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 ReviewOverview
GeForce GTX 660 v2 is a Performance Graphics Card based on the Kepler Architecture.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU. GPU
It equips a GPU GK106-450-A1 which has 5 Stream Multiprocessors activated and thus offers 960 Shader Processing Units, 80 TMUs and 24 ROPs. The Central Unit is initially clocked at 993MHz and goes up to 1058MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1502MHz.

Power Consumption
With a rated board TDP of 140W, it requires at least a 450W PSU with one available 6-pin connector.

Performance
GeForce GTX 660 v2 is only very slightly faster than GeForce GTX 660.

System Suggestions
GeForce GTX 660 v2 is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
GeForce GTX 750 Zotac 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 1033MHz, while the Turbo Boost is now of 1111MHz, 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 1% better than the reference NVIDIA GeForce GTX 750 and thus Radeon R7 260X is still faster.
