Compare any two graphics cards:
Radeon R9 270 vs Radeon RX 470
IntroThe Radeon R9 270 features core clock speeds of 900 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 memory. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.
Compare all that to the Radeon RX 470, which features a GPU core clock speed of 926 MHz, and 8192 MB of GDDR5 RAM running at 1650 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 470, in theory, should perform a bit faster than the Radeon R9 270 overall. (explain)
Texel RateThe Radeon RX 470 is quite a bit (about 65%) better at AF than the Radeon R9 270. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon RX 470 is superior to the Radeon R9 270, but only just. (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 data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 are applied per second. This number is calculated by multiplying the total amount of texture units 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 processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
