Compare any two graphics cards:
Radeon R9 380 2G vs Radeon RX 470
IntroThe Radeon R9 380 2G features clock speeds of 970 MHz on the GPU, and 1425 MHz on the 2048 MB of GDDR5 memory. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.
Compare all that to the Radeon RX 470, which uses a 14 nm design. AMD has clocked the core frequency at 926 MHz. The GDDR5 RAM is set to run 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 will be 16% quicker than the Radeon R9 380 2G overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon RX 470 should be just a bit (about 9%) better at texture filtering than the Radeon R9 380 2G. (explain)
Pixel RateThe Radeon R9 380 2G should be just a bit (about 5%) better at anti-aliasing than the Radeon RX 470, and should be capable of handling 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 are applied in one second. This number is worked out by multiplying the total texture units 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 applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
