Compare any two graphics cards:
GeForce GTX 275 vs GeForce GTX 470
IntroThe GeForce GTX 275 has a GPU core clock speed of 633 MHz, and the 896 MB of GDDR3 RAM is set to run at 1134 MHz through a 448-bit bus. It also is comprised of 240 Stream Processors, 80 Texture Address Units, and 28 Raster Operation Units.Compare those specs to the GeForce GTX 470, which has clock speeds of 607 MHz on the GPU, and 837 MHz on the 1280 MB of GDDR5 RAM. It features 448 SPUs as well as 56 TAUs and 40 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 470 should theoretically be just a bit better than the GeForce GTX 275 in general. (explain)
Texel RateThe GeForce GTX 275 should be much (approximately 49%) better at anisotropic filtering than the GeForce GTX 470. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 470 is superior to the GeForce GTX 275, by a large margin. (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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
