Compare any two graphics cards:
Radeon HD 6790 vs Radeon RX 550
IntroThe Radeon HD 6790 uses a 40 nm design. AMD has clocked the core frequency at 840 MHz. The GDDR5 RAM is set to run at a frequency of 1050 MHz on this specific card. It features 800 SPUs as well as 40 Texture Address Units and 16 ROPs.Compare all of that to the Radeon RX 550, which has a GPU core clock speed of 1100 MHz, and 2048 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 512 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6790 should theoretically be a bit better than the Radeon RX 550 overall. (explain)
Texel RateThe Radeon RX 550 should be a bit (approximately 5%) faster with regards to texture filtering than the Radeon HD 6790. (explain)
Pixel RateThe Radeon RX 550 should be a lot (about 31%) more effective at full screen anti-aliasing than the Radeon HD 6790, and able to handle higher screen resolutions better. (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 information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be processed per second. This is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
