Compare any two graphics cards:
GeForce GTX 560 vs Radeon HD 6870
IntroThe GeForce GTX 560 makes use of a 40 nm design. nVidia has set the core speed at 810 MHz. The GDDR5 memory is set to run at a speed of 1001 MHz on this specific card. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.
Compare that to the Radeon HD 6870, which has a clock frequency of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is comprised of 1120 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 6870 should in theory be a little bit better than the GeForce GTX 560 in general. (explain)
Texel RateThe Radeon HD 6870 will be a small bit (more or less 11%) more effective at texture filtering than the GeForce GTX 560. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6870 is a better choice, but not 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
