GeForce RTX 3080 vs Radeon RX 5600 XT

Intro

Compare all that to the Radeon RX 5600 XT, which comes with a core clock speed of 1375 MHz and a GDDR6 memory frequency of 1500 MHz. It also makes use of a 192-bit memory bus, and makes use of a 7 nm design. It is comprised of 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 193680 (98%)

Pixel Rate

The GeForce RTX 3080 should be much (approximately 57%) faster with regards to full screen anti-aliasing than the Radeon RX 5600 XT, and also capable of handling higher screen resolutions more effectively. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 50240 (57%)

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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
