Compare any two graphics cards:
GeForce GTX 470 vs GeForce GTX 650
IntroThe GeForce GTX 470 makes use of a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 RAM works at a speed of 837 MHz on this particular card. It features 448 SPUs along with 56 Texture Address Units and 40 Rasterization Operator Units.
Compare those specifications to the GeForce GTX 650, which has a core clock frequency of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 470 is 67% quicker than the GeForce GTX 650 overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 470 should be a little bit (about 0%) better at AF than the GeForce GTX 650. (explain)
Pixel RateThe GeForce GTX 470 should be a lot (approximately 43%) faster with regards to AA than the GeForce GTX 650, and should be capable of handling 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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
