Compare any two graphics cards:
Radeon R9 380 4G vs Radeon RX 470
IntroThe Radeon R9 380 4G uses a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 RAM is set to run at a speed of 1425 MHz on this specific model. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.
Compare that to the Radeon RX 470, which has core speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 RAM. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon RX 470 should in theory be a little bit superior to the Radeon R9 380 4G in general. (explain)
Texel RateThe Radeon RX 470 will be a little bit (approximately 9%) more effective at texture filtering than the Radeon R9 380 4G. (explain)
Pixel RateThe Radeon R9 380 4G should be a small bit (more or less 5%) better at full screen anti-aliasing than the Radeon RX 470, and also will be 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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
