GeForce RTX 2080 SUPER vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which features 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 Rasterization Operator Units.

Radeon RX 550		114688 MB/sec
	Difference: 393216 (343%)

Texel Rate

The GeForce RTX 2080 SUPER is a lot (about 800%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 281600 (800%)

Pixel Rate

The GeForce RTX 2080 SUPER should be much (more or less 500%) better at AA than the Radeon RX 550, and also will be capable of handling higher resolutions more effectively. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 88000 (500%)

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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
