Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 5870
IntroThe GeForce GTX 470 has a clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also features a 320-bit bus, and makes use of a 40 nm design. It features 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.Compare those specifications to the Radeon HD 5870, which uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory runs at a speed of 1200 MHz on this specific model. It features 1600(320x5) SPUs as well as 80 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 5870 should perform a little bit faster than the GeForce GTX 470 in general. (explain)
Texel RateThe Radeon HD 5870 is quite a bit (about 100%) better at anisotropic filtering than the GeForce GTX 470. (explain)
Pixel RateThe Radeon HD 5870 will be just a bit (approximately 12%) more effective at AA than the GeForce GTX 470, and capable of handling higher 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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
