Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 660
IntroThe GeForce GTX 460 uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory runs at a frequency of 900 MHz on this card. It features 336 SPUs along with 56 TAUs and 24 Rasterization Operator Units.
Compare those specs to the GeForce GTX 660, which uses a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this specific model. It features 960 SPUs as well as 80 Texture Address Units and 24 Rasterization Operator Units.

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 higher data rate. (explain)
Texel RateThe GeForce GTX 660 should be a lot (about 107%) faster with regards to AF than the GeForce GTX 460. (explain)
Pixel RateThe GeForce GTX 660 will be quite a bit (more or less 45%) more effective at FSAA than the GeForce GTX 460, and also will be able to handle higher 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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 are applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
