Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon HD 6970
IntroThe GeForce GTX 560 Ti 448 has core clock speeds of 732 MHz on the GPU, and 900 MHz on the 1280 MB of GDDR5 memory. It features 448 SPUs along with 56 Texture Address Units and 40 Rasterization Operator Units.Compare all of that to the Radeon HD 6970, which features clock speeds of 880 MHz on the GPU, and 1375 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6970 will be 22% faster than the GeForce GTX 560 Ti 448 overall, due to its higher data rate. (explain)
Texel RateThe Radeon HD 6970 will be a lot (more or less 106%) better at AF than the GeForce GTX 560 Ti 448. (explain)
Pixel RateThe GeForce GTX 560 Ti 448 is a little bit (approximately 4%) more effective at AA than the Radeon HD 6970, and also will be able to handle higher screen resolutions without losing too much performance. (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 MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
