GeForce RTX 3080 Ti vs Radeon RX 7900 XT

Intro

Compare those specs to the Radeon RX 7900 XT, which makes use of a 5 nm design. AMD has set the core frequency at 1500 MHz. The GDDR6 memory works at a frequency of 2500 MHz on this card. It features 5376 SPUs along with 336 Texture Address Units and 192 ROPs.

Radeon RX 7900 XT		300 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 50 Watts (17%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 Ti should be 14% faster than the Radeon RX 7900 XT in general, due to its greater bandwidth. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon RX 7900 XT		819200 MB/sec
	Difference: 115097 (14%)

Texel Rate

The Radeon RX 7900 XT is just a bit (more or less 15%) more effective at texture filtering than the GeForce RTX 3080 Ti. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce RTX 3080 Ti		436800 Mtexels/sec
	Difference: 67200 (15%)

Pixel Rate

The Radeon RX 7900 XT is a lot (approximately 88%) faster with regards to AA than the GeForce RTX 3080 Ti, and capable of handling higher screen resolutions better. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce RTX 3080 Ti		152880 Mpixels/sec
	Difference: 135120 (88%)

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 (counted in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
