Compare any two graphics cards:
Geforce GTX 680 vs Radeon HD 7870
IntroThe Geforce GTX 680 uses a 28 nm design. nVidia has clocked the core speed at 1006 MHz. The GDDR5 RAM works at a frequency of 1502 MHz on this specific model. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.
Compare those specifications to the Radeon HD 7870, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory is set to run at a speed of 1200 MHz on this card. It features 1280 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 680 should theoretically perform quite a bit faster than the Radeon HD 7870 in general. (explain)
Texel RateThe Geforce GTX 680 is a lot (approximately 61%) more effective at anisotropic filtering than the Radeon HD 7870. (explain)
Pixel RateIf running with a high resolution is important to you, then the Geforce GTX 680 is a better choice, but only just. (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 data (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at 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 the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
