Compare any two graphics cards:
GeForce GTX 460 2GB vs GeForce GTX 470
IntroThe GeForce GTX 460 2GB uses a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 RAM runs at a frequency of 900 MHz on this particular model. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.Compare those specs to the GeForce GTX 470, which features a clock frequency of 607 MHz and a GDDR5 memory speed of 837 MHz. It also uses a 320-bit memory bus, and uses a 40 nm design. It is comprised of 448 SPUs, 56 TAUs, and 40 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 470 is 16% faster than the GeForce GTX 460 2GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 460 2GB should be a bit (about 11%) faster with regards to texture filtering than the GeForce GTX 470. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 470 is the winner, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
