GeForce RTX 2080 SUPER vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which features GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also features 512 SPUs, 32 TAUs, and 16 ROPs.

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

Texel Rate

The GeForce RTX 2080 SUPER should be much (more or less 800%) better at texture 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 quite a bit (approximately 500%) more effective at full screen anti-aliasing than the Radeon RX 550, and also capable of handling higher resolutions without slowing down too much. (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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
