Compare any two graphics cards:
Radeon R9 380 4G vs Radeon RX 470
IntroThe Radeon R9 380 4G comes with core clock speeds of 970 MHz on the GPU, and 1425 MHz on the 4096 MB of GDDR5 memory. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.
Compare all that to the Radeon RX 470, which comes with core speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 470 should in theory perform a small bit faster than the Radeon R9 380 4G in general. (explain)
Texel RateThe Radeon RX 470 is just a bit (more or less 9%) more effective at AF than the Radeon R9 380 4G. (explain)
Pixel RateThe Radeon R9 380 4G will be just a bit (approximately 5%) better at FSAA than the Radeon RX 470, and should be capable of handling higher screen resolutions without losing too much performance. (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 (counted in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high 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 clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
