Compare any two graphics cards:
GeForce GTX 580 vs Geforce GTX 670
IntroThe GeForce GTX 580 comes with clock speeds of 772 MHz on the GPU, and 1002 MHz on the 1536 MB of GDDR5 memory. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.
Compare that to the Geforce GTX 670, which features a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1500 MHz through a 256-bit bus. It also is comprised of 1344 Stream Processors, 112 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 580 should in theory be a little bit better than the Geforce GTX 670 in general. (explain)
Texel RateThe Geforce GTX 670 is quite a bit (approximately 107%) better at AF than the GeForce GTX 580. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 580 is superior to the Geforce GTX 670, and very much so. (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 information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
