Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon RX 5500 XT
IntroThe Radeon HD 7870 XT makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this specific model. It features 1536 SPUs along with 96 Texture Address Units and 32 ROPs.Compare that to the Radeon RX 5500 XT, which has a GPU core clock speed of 1717 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 128-bit bus. It also features 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 5500 XT should in theory perform a little bit faster than the Radeon HD 7870 XT in general. (explain)
Texel RateThe Radeon RX 5500 XT will be quite a bit (about 70%) more effective at AF than the Radeon HD 7870 XT. (explain)
Pixel RateThe Radeon RX 5500 XT will be quite a bit (more or less 86%) better at full screen anti-aliasing than the Radeon HD 7870 XT, and also capable of handling higher resolutions without slowing down too much. (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 megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out 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 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 maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
