Compare any two graphics cards:
Radeon HD 4890 2GB vs Radeon RX 560
IntroThe Radeon HD 4890 2GB has core clock speeds of 1000 MHz on the GPU, and 975 MHz on the 2048 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon RX 560, which has a GPU core clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4890 2GB should in theory perform a little bit faster than the Radeon RX 560 overall. (explain)
Texel RateThe Radeon RX 560 is quite a bit (approximately 88%) faster with regards to texture filtering than the Radeon HD 4890 2GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon RX 560 is a better choice, though only just barely. (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 largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that can be applied in one second. This is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
