Compare any two graphics cards:
Radeon HD 4890 1GB vs Radeon RX 550
IntroThe Radeon HD 4890 1GB comes with a GPU core speed of 1000 MHz, and the 1024 MB of GDDR5 RAM is set to run at 975 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.Compare that to the Radeon RX 550, which has a core clock speed of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and uses a 14 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4890 1GB should perform a bit faster than the Radeon RX 550 in general. (explain)
Texel RateThe Radeon HD 4890 1GB will be a bit (approximately 14%) better at texture filtering than the Radeon RX 550. (explain)
Pixel RateThe Radeon RX 550 should be a small bit (more or less 10%) faster with regards to full screen anti-aliasing than the Radeon HD 4890 1GB, and should be able to handle higher screen 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 (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that are applied in one second. This number 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
