Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 4870 512MB
IntroThe GeForce GTX 470 features a GPU core clock speed of 607 MHz, and the 1280 MB of GDDR5 memory runs at 837 MHz through a 320-bit bus. It also is made up of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.Compare those specifications to the Radeon HD 4870 512MB, which makes use of a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR5 RAM runs at a frequency of 900 MHz on this specific card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 470 should be 16% faster than the Radeon HD 4870 512MB in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 470 is just a bit (about 13%) more effective at anisotropic filtering than the Radeon HD 4870 512MB. (explain)
Pixel RateThe GeForce GTX 470 is quite a bit (about 102%) more effective at anti-aliasing than the Radeon HD 4870 512MB, and capable of handling higher screen resolutions without slowing down too much. (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 max amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
