Compare any two graphics cards:
GeForce GTX 580 vs Radeon HD 3470 512MB
IntroThe GeForce GTX 580 features a GPU core clock speed of 772 MHz, and the 1536 MB of GDDR5 RAM is set to run at 1002 MHz through a 384-bit bus. It also is made up of 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.Compare those specs to the Radeon HD 3470 512MB, which has a clock speed of 800 MHz and a GDDR3 memory frequency of 950 MHz. It also uses a 128-bit memory bus, and uses a 55 nm design. It features 40(8x5) SPUs, 4 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the GeForce GTX 580 should in theory be much better than the Radeon HD 3470 512MB overall. (explain)
Texel RateThe GeForce GTX 580 will be a lot (about 1444%) faster with regards to AF than the Radeon HD 3470 512MB. (explain)
Pixel RateThe GeForce GTX 580 should be a lot (approximately 1058%) better at FSAA than the Radeon HD 3470 512MB, and also will be 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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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.
