Compare any two graphics cards:
Radeon HD 4850 X2 1GB vs Radeon RX 550
IntroThe Radeon HD 4850 X2 1GB features a GPU core clock speed of 625 MHz, and the 1024 MB of GDDR3 RAM is set to run at 993 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.Compare all of that to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular model. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4850 X2 1GB will be 11% quicker than the Radeon RX 550 overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 4850 X2 1GB is quite a bit (approximately 42%) more effective at anisotropic filtering than the Radeon RX 550. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 4850 X2 1GB is the winner, 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
