Radeon RX 550 vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which has GPU clock speed of 1968 MHz, and 8192 MB of GDDR6 RAM running at 2000 MHz through a 128-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 64 ROPs.

Radeon RX 550		114688 MB/sec
	Difference: 147456 (129%)

Texel Rate

The Radeon RX 6600 XT is quite a bit (more or less 616%) better at AF than the Radeon RX 550. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 216704 (616%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6600 XT is the winner, and very much so. (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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
