GeForce RTX 3080 Ti vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which comes with a GPU core clock speed of 1670 MHz, and 4096 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also features 1408 Stream Processors, 88 Texture Address Units, and 32 Raster Operation Units.

Radeon RX 5500		229376 MB/sec
	Difference: 704921 (307%)

Texel Rate

The GeForce RTX 3080 Ti should be much (approximately 197%) better at anisotropic filtering than the Radeon RX 5500. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 289840 (197%)

Pixel Rate

The GeForce RTX 3080 Ti is quite a bit (more or less 186%) better at anti-aliasing than the Radeon RX 5500, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 99440 (186%)

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 (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses 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, High Dynamic Range and high resolutions.

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

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