Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon RX 470
IntroThe Radeon HD 7870 XT makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this particular card. It features 1536 SPUs along with 96 TAUs and 32 ROPs.
Compare those specs to the Radeon RX 470, which features clock speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 RAM. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon RX 470 should perform just a bit faster than the Radeon HD 7870 XT overall. (explain)
Texel RateThe Radeon RX 470 will be much (approximately 33%) more effective at anisotropic filtering than the Radeon HD 7870 XT. (explain)
Pixel RateThe Radeon RX 470 will be a bit (more or less 0%) more effective at FSAA than the Radeon HD 7870 XT, and capable of handling higher screen resolutions more effectively. (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 information (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel 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 ability to get to the maximum fill rate.
