Compare any two graphics cards:
Radeon HD 4870 1GB vs Radeon RX 550
IntroThe Radeon HD 4870 1GB makes use of a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this model. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.Compare those specifications to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this particular model. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4870 1GB should be just a bit faster than the Radeon RX 550 in general. (explain)
Texel RateThe Radeon RX 550 is a small bit (more or less 17%) better at AF than the Radeon HD 4870 1GB. (explain)
Pixel RateThe Radeon RX 550 is a lot (more or less 47%) better at AA than the Radeon HD 4870 1GB, and also will be capable of handling higher resolutions more effectively. (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 moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
