Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 660
IntroThe GeForce GTX 460 makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 RAM works at a speed of 900 MHz on this specific model. It features 336 SPUs as well as 56 Texture Address Units and 24 ROPs.
Compare all of that to the GeForce GTX 660, which makes use of a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 memory is set to run at a frequency of 1502 MHz on this specific model. It features 960 SPUs as well as 80 Texture Address Units and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 660 should theoretically perform much faster than the GeForce GTX 460 overall. (explain)
Texel RateThe GeForce GTX 660 is quite a bit (approximately 107%) faster with regards to texture filtering than the GeForce GTX 460. (explain)
Pixel RateThe GeForce GTX 660 is a lot (more or less 45%) more effective at anti-aliasing than the GeForce GTX 460, and should be able to handle higher screen 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
