GeForce RTX 2080 SUPER vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which makes use of a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 memory works at a speed of 1750 MHz on this particular model. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Radeon RX 550		50 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 200 Watts (400%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER should be 343% quicker than the Radeon RX 550 in general, because of its higher bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 393216 (343%)

Texel Rate

The GeForce RTX 2080 SUPER will be much (about 800%) faster with regards to 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 will be much (more or less 500%) faster with regards to anti-aliasing than the Radeon RX 550, and will be capable of handling higher screen 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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, 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 that the graphics chip 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many 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.
