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 speed at 980 MHz. The GDDR5 RAM runs at a speed of 1502 MHz on this particular card. It features 960 SPUs as well as 80 Texture Address Units and 24 ROPs.Compare all of that to the GeForce GTX 750 Ti, which has a core clock speed of 1020 MHz and a GDDR5 memory frequency of 1350 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 660 should theoretically be much faster than the GeForce GTX 750 Ti overall. (explain)
Texel RateThe GeForce GTX 660 should be much (more or less 92%) more effective at AF than the GeForce GTX 750 Ti. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 660 is the winner, by a large margin. (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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
