In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 are significantly better than the AMD Radeon R7 260X v2 PowerColor OC 1GB Edition.

The R7 260X has a 50 MHz higher core clock speed than the GeForce GTX 660, but the GeForce GTX 660 has 24 more Texture Mapping Units than the R7 260X. As a result, the GeForce GTX 660 exhibits a 20.7 GTexel/s better Texture Fill Rate than the R7 260X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 260X has a 50 MHz higher core clock speed than the GeForce GTX 660, but the GeForce GTX 660 has 8 more Render Output Units than the R7 260X. As a result, the GeForce GTX 660 exhibits a 7 GPixel/s better Pixel Fill Rate than the R7 260X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 260X was released over a year more recently than the GeForce GTX 660, and so the R7 260X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 660.

The GeForce GTX 660 has 1024 MB more video memory than the R7 260X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 660 also has superior memory performance overall.

The GeForce GTX 660 has 48.2 GB/sec greater memory bandwidth than the R7 260X, which means that the memory performance of the GeForce GTX 660 is noticeably better than the R7 260X.

The Radeon R7 260X v2 PowerColor OC 1GB Edition has 896 Shader Processing Units and the GeForce GTX 660 has 960. However, the actual shader performance of the R7 260X is 784 and the actual shader performance of the GeForce GTX 660 is 992. The GeForce GTX 660 having 208 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 660 delivers a significantly smoother and more efficient experience when processing graphical data than the R7 260X.

The Radeon R7 260X v2 PowerColor OC 1GB Edition requires 105 Watts to run and the GeForce GTX 660 requires 140 Watts. We would recommend a PSU with at least 500 Watts for the R7 260X and a PSU with at least 450 Watts for the GeForce GTX 660. The GeForce GTX 660 requires 35 Watts more than the R7 260X to run. The difference is significant enough that the GeForce GTX 660 may have a slight adverse affect on your yearly electricity bills in comparison to the R7 260X.

Performance

Overview
GeForce GTX 660 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 GK106-400-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 980MHz and goes up to 1033MHz, 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 competes with Radeon HD 7850.
At 1920x1080, the best suited resolution for GeForce GTX 660, benchmarks indicate its performance is a little over the older GeForce GTX 570 and quite superior to Radeon HD 7850.

System Suggestions
GeForce GTX 660 is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
