Compare any two graphics cards:
GeForce GTX 660 vs GeForce GTX 780 Ti
IntroThe GeForce GTX 660 uses a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 RAM runs at a frequency of 1502 MHz on this specific model. It features 960 SPUs along with 80 Texture Address Units and 24 Rasterization Operator Units.Compare that to the GeForce GTX 780 Ti, which uses a 28 nm design. nVidia has clocked the core speed at 875 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this particular card. It features 2880 SPUs as well as 240 Texture Address Units and 48 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 780 Ti should be 133% quicker than the GeForce GTX 660 overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 780 Ti is much (more or less 168%) better at texture filtering than the GeForce GTX 660. (explain)
Pixel RateThe GeForce GTX 780 Ti will be a lot (more or less 79%) more effective at AA than the GeForce GTX 660, and also will be able to handle higher resolutions more effectively. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
