Compare any two graphics cards:
GeForce GTX 660 vs GeForce GTX 750 Ti
IntroThe GeForce GTX 660 has a clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 192-bit memory bus, and uses a 28 nm design. It is made up of 960 SPUs, 80 TAUs, and 24 Raster Operation Units.Compare those specs to the GeForce GTX 750 Ti, which comes with GPU clock speed of 1020 MHz, and 2048 MB of GDDR5 RAM set to run at 1350 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 660 should in theory be much faster than the GeForce GTX 750 Ti in general. (explain)
Texel RateThe GeForce GTX 660 is a lot (approximately 92%) faster with regards to texture filtering than the GeForce GTX 750 Ti. (explain)
Pixel RateThe GeForce GTX 660 is much (about 44%) more effective at full screen anti-aliasing than the GeForce GTX 750 Ti, and should be able to handle higher screen resolutions while still performing well. (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 information (measured in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
