Compare any two graphics cards:
Radeon R9 380 4G vs Radeon RX 470
IntroThe Radeon R9 380 4G makes use of a 28 nm design. AMD has clocked the core frequency at 970 MHz. The GDDR5 memory runs at a frequency of 1425 MHz on this particular model. It features 1792 SPUs along with 112 TAUs and 32 ROPs.
Compare those specifications to the Radeon RX 470, which has core 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 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 470 should theoretically be a small bit faster than the Radeon R9 380 4G in general. (explain)
Texel RateThe Radeon RX 470 will be just a bit (approximately 9%) faster with regards to texture filtering than the Radeon R9 380 4G. (explain)
Pixel RateThe Radeon R9 380 4G will be a small bit (approximately 5%) better at AA than the Radeon RX 470, and also able to handle higher screen resolutions without slowing down too much. (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 maximum amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied 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 better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
