Compare any two graphics cards:
GeForce GTX 660 vs GeForce GTX 750 Ti
IntroThe GeForce GTX 660 makes use of a 28 nm design. nVidia has clocked the core frequency at 980 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this particular card. It features 960 SPUs along with 80 TAUs and 24 ROPs.Compare those specs to the GeForce GTX 750 Ti, which makes use of a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 RAM is set to run at a speed of 1350 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 660 should in theory be a lot better than the GeForce GTX 750 Ti in general. (explain)
Texel RateThe GeForce GTX 660 will be quite a bit (approximately 92%) more effective at AF than the GeForce GTX 750 Ti. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 660 is the winner, and very much so. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
