Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 660
IntroThe GeForce GTX 460 comes with a GPU core clock speed of 675 MHz, and the 768 MB of GDDR5 memory is set to run at 900 MHz through a 192-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 24 Raster Operation Units.
Compare those specs to the GeForce GTX 660, which makes use of a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this specific card. It features 960 SPUs along with 80 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 660 should be 67% faster than the GeForce GTX 460 in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 660 should be much (about 107%) faster with regards to anisotropic filtering than the GeForce GTX 460. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 660 is superior to the GeForce GTX 460, by far. (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.

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