Compare any two graphics cards:
Geforce GTX 680 vs Radeon HD 7950
IntroThe Geforce GTX 680 makes use of a 28 nm design. nVidia has clocked the core speed at 1006 MHz. The GDDR5 RAM is set to run at a speed of 1502 MHz on this particular model. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.
Compare those specs to the Radeon HD 7950, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a speed of 1250 MHz on this particular card. It features 1792 SPUs as well as 112 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 7950 should in theory be a lot faster than the Geforce GTX 680 in general. (explain)
Texel RateThe Geforce GTX 680 will be much (more or less 44%) more effective at AF than the Radeon HD 7950. (explain)
Pixel RateThe Geforce GTX 680 is much (about 26%) more effective at AA than the Radeon HD 7950, and will be able to handle higher screen resolutions better. (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 max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
