Compare any two graphics cards:
GeForce GTX 1080 vs GeForce GTX 970
IntroThe GeForce GTX 1080 makes use of a 16 nm design. nVidia has set the core frequency at 1607 MHz. The GDDR5X memory works at a speed of 1251 MHz on this specific card. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.
Compare all of that to the GeForce GTX 970, which comes with a core clock speed of 1050 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1664 SPUs, 104 Texture Address Units, and 64 ROPs.

As far as performance goes, the GeForce GTX 1080 should theoretically be much better than the GeForce GTX 970 overall. (explain)
Texel RateThe GeForce GTX 1080 will be quite a bit (approximately 135%) faster with regards to texture filtering than the GeForce GTX 970. (explain)
Pixel RateThe GeForce GTX 1080 should be much (about 53%) better at full screen anti-aliasing than the GeForce GTX 970, and also 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 max amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
