GeForce RTX 2080 SUPER vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which uses a 5 nm design. AMD has set the core frequency at 1500 MHz. The GDDR6 memory is set to run at a speed of 2500 MHz on this particular model. It features 5376 SPUs along with 336 Texture Address Units and 192 ROPs.

GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 187200 (59%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 7900 XT is a better choice, and very much so. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 182400 (173%)

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 information (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of 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 per second.

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