Compare any two graphics cards:
Radeon HD 7970 vs Radeon RX 580
IntroThe Radeon HD 7970 has a clock frequency of 925 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 384-bit bus, and makes use of a 28 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.Compare those specs to the Radeon RX 580, which comes with a GPU core clock speed of 1257 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also is made up of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 7970 should theoretically be a little bit superior to the Radeon RX 580 overall. (explain)
Texel RateThe Radeon RX 580 will be quite a bit (approximately 53%) faster with regards to AF than the Radeon HD 7970. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon RX 580 is a better choice, and very much so. (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 largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
