Compare any two graphics cards:
Radeon HD 4790 vs Radeon RX 560
IntroThe Radeon HD 4790 comes with a GPU clock speed of 600 MHz, and the 512 MB of GDDR5 RAM is set to run at 800 MHz through a 256-bit bus. It also is made up of 640(128x5) Stream Processors, 32 TAUs, and 16 Raster Operation Units.Compare that to the Radeon RX 560, which comes with a clock speed of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It features 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon RX 560, in theory, should be a little bit faster than the Radeon HD 4790 in general. (explain)
Texel RateThe Radeon RX 560 should be quite a bit (about 292%) more effective at anisotropic filtering than the Radeon HD 4790. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon RX 560 is the winner, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses 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 high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few 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.
