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 set the core speed at 925 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this specific card. It features 1536 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.
Compare that to the Radeon RX 470, which makes use of a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory runs at a frequency of 1650 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon RX 470 should perform a small bit faster than the Radeon HD 7870 XT in general. (explain)
Texel RateThe Radeon RX 470 should be a lot (about 33%) more effective at texture filtering than the Radeon HD 7870 XT. (explain)
Pixel RateThe Radeon RX 470 is a small bit (about 0%) faster with regards to anti-aliasing than the Radeon HD 7870 XT, and capable of handling higher screen resolutions while still performing well. (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 (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result 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, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core 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 amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
