Compare any two graphics cards:
Radeon HD 4730 vs Radeon RX 550
IntroThe Radeon HD 4730 features a GPU clock speed of 700 MHz, and the 512 MB of GDDR5 memory is set to run at 900 MHz through a 128-bit bus. It also features 640(128x5) SPUs, 32 TAUs, and 8 ROPs.Compare those specifications to the Radeon RX 550, which comes with a GPU core clock speed of 1100 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon RX 550 should theoretically be a lot superior to the Radeon HD 4730 overall. (explain)
Texel RateThe Radeon RX 550 will be much (more or less 57%) more effective at anisotropic filtering than the Radeon HD 4730. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon RX 550 is the winner, 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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the 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 maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
