Geforce GTX 1080 Ti vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has clocked the core speed at 1825 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this particular card. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Geforce GTX 1080 Ti		495616 MB/sec
	Difference: 28672 (6%)

Texel Rate

The Radeon RX 6900 XT will be a lot (more or less 76%) better at anisotropic filtering than the Geforce GTX 1080 Ti. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Geforce GTX 1080 Ti		331520 Mtexels/sec
	Difference: 252480 (76%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6900 XT is superior to the Geforce GTX 1080 Ti, by far. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Geforce GTX 1080 Ti		130240 Mpixels/sec
	Difference: 103360 (79%)

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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better 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 record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 maximum fill rate.
