Compare any two graphics cards:
Radeon HD 7970 vs Radeon RX 470 4GB
IntroThe Radeon HD 7970 makes use of a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 RAM is set to run at a speed of 1375 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.Compare those specifications to the Radeon RX 470 4GB, which has a core clock speed of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also uses a 256-bit bus, and uses a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 7970 should in theory be quite a bit superior to the Radeon RX 470 4GB in general. (explain)
Texel RateThe Radeon RX 470 4GB will be a small bit (about 0%) better at AF than the Radeon HD 7970. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon RX 470 4GB is superior to the Radeon HD 7970, 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: Bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 worked out by multiplying the total texture units 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 processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
