Compare any two graphics cards:
GeForce GTX 970 vs GeForce GTX 980
IntroThe GeForce GTX 970 uses a 28 nm design. nVidia has set the core speed at 1050 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this particular model. It features 1664 SPUs as well as 104 Texture Address Units and 64 ROPs.
Compare all that to the GeForce GTX 980, which makes use of a 28 nm design. nVidia has set the core frequency at 1126 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have the exact same bandwidth, so in theory they should perform the same. (explain)
Texel RateThe GeForce GTX 980 will be quite a bit (more or less 32%) more effective at texture filtering than the GeForce GTX 970. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 980 is superior to the GeForce GTX 970, though not 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.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock 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 processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 maximum fill rate.
