GeForce RTX 2080 SUPER vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which comes with core speeds of 1500 MHz on the GPU, and 2500 MHz on the 20480 MB of GDDR6 memory. It features 5376 SPUs along with 336 TAUs and 192 Rasterization Operator Units.

GeForce RTX 2080 SUPER		507904 MB/sec
	Difference: 311296 (61%)

Texel Rate

The Radeon RX 7900 XT is quite a bit (approximately 59%) more effective at AF than the GeForce RTX 2080 SUPER. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 187200 (59%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 7900 XT is the winner, by a large margin. (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 largest amount of data (in units of 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 the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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