Compare any two graphics cards:
Radeon R9 390X 8G vs Radeon RX 470 4GB
IntroThe Radeon R9 390X 8G makes use of a 28 nm design. AMD has clocked the core frequency at 1050 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this model. It features 2816 SPUs along with 176 Texture Address Units and 64 ROPs.Compare those specifications to the Radeon RX 470 4GB, which has a core clock speed of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also features a 256-bit bus, and uses a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 390X 8G should be 82% quicker than the Radeon RX 470 4GB in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon R9 390X 8G is quite a bit (about 56%) more effective at AF than the Radeon RX 470 4GB. (explain)
Pixel RateThe Radeon R9 390X 8G is much (approximately 127%) faster with regards to FSAA than the Radeon RX 470 4GB, and able to handle higher resolutions more effectively. (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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
