Compare any two graphics cards:
Radeon R9 270 vs Radeon RX 470
IntroThe Radeon R9 270 has a core clock speed of 900 MHz and a GDDR5 memory speed of 1400 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It features 1280 SPUs, 80 TAUs, and 32 ROPs.
Compare all of that to the Radeon RX 470, which features GPU clock speed of 926 MHz, and 8192 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon RX 470 should theoretically be a bit better than the Radeon R9 270 in general. (explain)
Texel RateThe Radeon RX 470 will be a lot (approximately 65%) faster with regards to texture filtering than the Radeon R9 270. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon RX 470 is the winner, but it probably won't make a huge difference. (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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 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 high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
