Compare any two graphics cards:
GeForce GTX 480 vs Radeon HD 5870
IntroThe GeForce GTX 480 features a core clock frequency of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also features a 384-bit bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 60 TAUs, and 48 ROPs.Compare all of that to the Radeon HD 5870, which has core speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 RAM. It features 1600(320x5) SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 480 wins(Based entirely on the benchmarks listed above)When combining all game benchmark scores on this page together, the GeForce GTX 480 wins overall, by 74 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 480 should theoretically be just a bit better than the Radeon HD 5870 overall. (explain)
Texel RateThe Radeon HD 5870 should be much (about 62%) better at anisotropic filtering than the GeForce GTX 480. (explain)
Pixel RateThe GeForce GTX 480 should be a lot (approximately 24%) more effective at anti-aliasing than the Radeon HD 5870, and also should be able to handle 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.

Specifications
Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should 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 anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
