	Difference: 151680 (79%)

Texel Rate

The Radeon RX 5600 XT is quite a bit (approximately 301%) better at AF than the GeForce GTX 580 3GB. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 148592 (301%)

Pixel Rate

The Radeon RX 5600 XT will be quite a bit (about 137%) better at full screen anti-aliasing than the GeForce GTX 580 3GB, and also capable of handling higher screen resolutions better. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 50944 (137%)

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 maximum amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
