Compare any two graphics cards:
Radeon HD 4890 2GB vs Radeon RX 560
IntroThe Radeon HD 4890 2GB makes use of a 55 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory runs at a frequency of 975 MHz on this card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon RX 560, which makes use of a 14 nm design. AMD has set the core speed at 1175 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this particular card. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4890 2GB should theoretically perform just a bit faster than the Radeon RX 560 overall. (explain)
Texel RateThe Radeon RX 560 is quite a bit (about 88%) faster with regards to AF than the Radeon HD 4890 2GB. (explain)
Pixel RateThe Radeon RX 560 should be just a bit (about 18%) better at AA than the Radeon HD 4890 2GB, and should be capable of handling higher screen resolutions better. (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 max amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
