Compare any two graphics cards:
Geforce GTX 780 vs Radeon HD 7950
IntroThe Geforce GTX 780 features a core clock frequency of 863 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It features 2304 SPUs, 192 Texture Address Units, and 48 Raster Operation Units.
Compare that to the Radeon HD 7950, which features a GPU core clock speed of 800 MHz, and 1536 MB of GDDR5 memory running at 1250 MHz through a 384-bit bus. It also is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 780 will be 20% faster than the Radeon HD 7950 overall, because of its higher bandwidth. (explain)
Texel RateThe Geforce GTX 780 will be much (more or less 85%) faster with regards to AF than the Radeon HD 7950. (explain)
Pixel RateIf using a high resolution is important to you, then the Geforce GTX 780 is a better choice, by a large margin. (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 (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
