Radeon RX 5500 XT vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which has GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also is made up of 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 432904 (287%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6900 XT is superior to the Radeon RX 5500 XT, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 178656 (325%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
