Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 470
IntroThe GeForce GTX 280 uses a 65 nm design. nVidia has clocked the core frequency at 602 MHz. The GDDR3 RAM works at a speed of 1107 MHz on this specific model. It features 240 SPUs along with 80 Texture Address Units and 32 ROPs.Compare that to the GeForce GTX 470, which has a clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also features a 320-bit memory bus, and uses a 40 nm design. It features 448 SPUs, 56 TAUs, and 40 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 280 should be 6% faster than the GeForce GTX 470 in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 280 is quite a bit (approximately 42%) more effective at anisotropic filtering than the GeForce GTX 470. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 470 is superior to the GeForce GTX 280, by far. (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 moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
