Compare any two graphics cards:
Radeon R9 380 2G vs Radeon RX 470
IntroThe Radeon R9 380 2G makes use of a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 RAM runs at a speed of 1425 MHz on this particular model. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.
Compare those specs 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 works at a frequency of 1650 MHz on this specific 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 be a small bit faster than the Radeon R9 380 2G overall. (explain)
Texel RateThe Radeon RX 470 will be a small bit (more or less 9%) better at texture filtering than the Radeon R9 380 2G. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 380 2G is superior to the Radeon RX 470, not by a very large margin though. (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 information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
