GeForce RTX 3080 vs Radeon RX 5500 XT

Intro

Compare all of that to the Radeon RX 5500 XT, which has core clock speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

Radeon RX 5500 XT		229376 MB/sec
	Difference: 549171 (239%)

Texel Rate

The GeForce RTX 3080 will be quite a bit (about 159%) more effective at AF than the Radeon RX 5500 XT. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 240584 (159%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 3080 is a better choice, and very much so. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 83296 (152%)

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 moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
