Compare any two graphics cards:
Radeon R9 285 vs Radeon RX 470
IntroThe Radeon R9 285 comes with core clock speeds of 918 MHz on the GPU, and 1375 MHz on the 2048 MB of GDDR5 RAM. It features 1792 SPUs along with 112 Texture Address Units and 32 Rasterization Operator Units.
Compare those specs to the Radeon RX 470, which uses a 14 nm design. AMD has clocked the core speed at 926 MHz. The GDDR5 memory works at a speed of 1650 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon RX 470 should in theory be a small bit better than the Radeon R9 285 in general. (explain)
Texel RateThe Radeon RX 470 should be a bit (approximately 15%) more effective at AF than the Radeon R9 285. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon RX 470 is superior to the Radeon R9 285, though not by far. (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 card's bus width by the speed of its memory. If it uses DDR memory, the result 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core 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 processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
