GeForce RTX 3080 Ti vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which comes with core speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

	Difference: 300 Watts (600%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti will be 715% quicker than the Radeon RX 550 overall, because of its greater bandwidth. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 819609 (715%)

Texel Rate

The GeForce RTX 3080 Ti is quite a bit (about 1141%) better at texture filtering than the Radeon RX 550. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 401600 (1141%)

Pixel Rate

The GeForce RTX 3080 Ti will be much (more or less 769%) more effective at AA than the Radeon RX 550, and will be capable of handling higher screen resolutions better. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 135280 (769%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
