Compare any two graphics cards:
Radeon R9 285 vs Radeon RX 470
IntroThe Radeon R9 285 has a clock frequency of 918 MHz and a GDDR5 memory speed of 1375 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 ROPs.
Compare that to the Radeon RX 470, which comes with a core clock speed of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also uses a 256-bit bus, and makes use of a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 470, in theory, should be just a bit faster than the Radeon R9 285 overall. (explain)
Texel RateThe Radeon RX 470 should be a little bit (approximately 15%) more effective at anisotropic filtering than the Radeon R9 285. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon RX 470 is a better choice, 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
