Compare any two graphics cards:
GeForce GTX 580 3GB vs Radeon HD 5770
IntroThe GeForce GTX 580 3GB comes with a GPU core clock speed of 772 MHz, and the 3072 MB of GDDR5 RAM runs at 1002 MHz through a 384-bit bus. It also features 512 Stream Processors, 64 Texture Address Units, and 48 Raster Operation Units.Compare all that to the Radeon HD 5770, which has a clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 580 3GB should in theory be quite a bit better than the Radeon HD 5770 in general. (explain)
Texel RateThe GeForce GTX 580 3GB should be quite a bit (about 45%) faster with regards to anisotropic filtering than the Radeon HD 5770. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 580 3GB is a better choice, 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
