Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 650
IntroThe GeForce GTX 460 features a GPU core clock speed of 675 MHz, and the 768 MB of GDDR5 RAM is set to run at 900 MHz through a 192-bit bus. It also is made up of 336 SPUs, 56 Texture Address Units, and 24 Raster Operation Units.
Compare those specifications to the GeForce GTX 650, which features GPU clock speed of 1058 MHz, and 1024 MB of GDDR5 memory set to run at 1250 MHz through a 128-bit bus. It also features 384 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 460 will be 8% quicker than the GeForce GTX 650 in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 460 should be a bit (about 12%) more effective at AF than the GeForce GTX 650. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 650 is superior to the GeForce GTX 460, but it probably won't make a huge difference. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
