Compare any two graphics cards:
GeForce GTX 580 3GB vs GeForce GTX 970
IntroThe GeForce GTX 580 3GB makes use of a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 RAM runs at a speed of 1002 MHz on this card. It features 512 SPUs as well as 64 Texture Address Units and 48 Rasterization Operator Units.Compare all of that to the GeForce GTX 970, which comes with GPU clock speed of 1050 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also is made up of 1664 Stream Processors, 104 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 970 is 16% quicker than the GeForce GTX 580 3GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 970 is much (about 121%) better at AF than the GeForce GTX 580 3GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 970 is the winner, by far. (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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
