Compare any two graphics cards:
Geforce GTX 680 vs Radeon HD 6970
IntroThe Geforce GTX 680 features a GPU core speed of 1006 MHz, and the 2048 MB of GDDR5 memory runs at 1502 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.Compare all of that to the Radeon HD 6970, which comes with a GPU core clock speed of 880 MHz, and 2048 MB of GDDR5 memory running at 1375 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 96 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Geforce GTX 680 should in theory be a bit faster than the Radeon HD 6970 in general. (explain)
Texel RateThe Geforce GTX 680 will be a lot (more or less 52%) better at anisotropic filtering than the Radeon HD 6970. (explain)
Pixel RateThe Geforce GTX 680 is a small bit (more or less 14%) better at AA than the Radeon HD 6970, and also should be capable of handling higher screen resolutions more effectively. (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 max amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
