Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 6970
IntroThe Geforce GTX 670 makes use of a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this model. It features 1344 SPUs along with 112 TAUs and 32 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6970, which comes with GPU clock speed of 880 MHz, and 2048 MB of GDDR5 RAM set to run at 1375 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 96 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Geforce GTX 670 should be just a bit faster than the Radeon HD 6970 overall. (explain)
Texel RateThe Geforce GTX 670 is a lot (more or less 21%) more effective at anisotropic filtering than the Radeon HD 6970. (explain)
Pixel RateThe Geforce GTX 670 should be a bit (about 4%) better at FSAA than the Radeon HD 6970, and capable of handling higher 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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 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, High Dynamic Range and higher screen 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 texture units by the core speed of the chip. The better this number, the better the 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 most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
