Compare any two graphics cards:
Radeon HD 7970 vs Radeon RX 590
IntroThe Radeon HD 7970 comes with a GPU core clock speed of 925 MHz, and the 3072 MB of GDDR5 memory runs at 1375 MHz through a 384-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.Compare that to the Radeon RX 590, which comes with core speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7970 should be a small bit faster than the Radeon RX 590 in general. (explain)
Texel RateThe Radeon RX 590 is much (more or less 79%) faster with regards to anisotropic filtering than the Radeon HD 7970. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon RX 590 is superior to the Radeon HD 7970, by a large margin. (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 (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card 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 applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
