Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 7970
IntroThe Geforce GTX 670 comes with a core clock frequency of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 32 ROPs.
Compare those specifications to the Radeon HD 7970, which features GPU core speed of 925 MHz, and 3072 MB of GDDR5 RAM running at 1375 MHz through a 384-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 7970 should be 38% quicker than the Geforce GTX 670 overall, because of its higher data rate. (explain)
Texel RateThe Radeon HD 7970 should be a bit (approximately 16%) more effective at texture filtering than the Geforce GTX 670. (explain)
Pixel RateThe Radeon HD 7970 is a bit (about 1%) more effective at FSAA than the Geforce GTX 670, and capable of handling higher 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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 can be processed 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the potential to reach the maximum fill rate.
