Radeon RX 550 vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which has GPU core speed of 1968 MHz, and 8192 MB of GDDR6 RAM set to run at 2000 MHz through a 128-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 550		35200 Mtexels/sec
	Difference: 216704 (616%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6600 XT is superior to the Radeon RX 550, by a large margin. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 108352 (616%)

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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
