Compare any two graphics cards:
GeForce GTX 560 vs Radeon HD 6870
IntroThe GeForce GTX 560 has a clock frequency of 810 MHz and a GDDR5 memory speed of 1001 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.
Compare all of that to the Radeon HD 6870, which comes with core speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 1120 SPUs as well as 56 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 6870 should theoretically be a little bit better than the GeForce GTX 560 overall. (explain)
Texel RateThe Radeon HD 6870 should be a bit (about 11%) faster with regards to anisotropic filtering than the GeForce GTX 560. (explain)
Pixel RateThe Radeon HD 6870 is a small bit (about 11%) more effective at anti-aliasing than the GeForce GTX 560, and also should be able to handle 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.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
