GeForce RTX 2080 vs Radeon RX 550

Intro

The GeForce RTX 2080 features a GPU core speed of 1515 MHz, and the 8192 MB of GDDR6 RAM is set to run at 14 MHz through a 256-bit bus. It also is made up of 2944 SPUs, 184 Texture Address Units, and 64 ROPs.

Compare those specifications to the Radeon RX 550, which features core clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

GeForce RTX 2080 458752 MB/sec
Radeon RX 550 114688 MB/sec
Difference: 344064 (300%)

Texel Rate

The GeForce RTX 2080 should be quite a bit (about 692%) faster with regards to anisotropic filtering than the Radeon RX 550. (explain)

GeForce RTX 2080 278760 Mtexels/sec
Radeon RX 550 35200 Mtexels/sec
Difference: 243560 (692%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 2080 is superior to the Radeon RX 550, and very much so. (explain)

GeForce RTX 2080 96960 Mpixels/sec
Radeon RX 550 17600 Mpixels/sec
Difference: 79360 (451%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its 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 speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many 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.
