Geforce GTX 1080 Ti vs Radeon RX 6900 XT

Intro

Compare those specs to the Radeon RX 6900 XT, which has a GPU core clock speed of 1825 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also features 5120 Stream Processors, 320 TAUs, and 128 ROPs.

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

Texel Rate

The Radeon RX 6900 XT should be a lot (about 76%) faster with regards to texture 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

The Radeon RX 6900 XT will be much (more or less 79%) more effective at AA than the Geforce GTX 1080 Ti, and able to handle higher screen resolutions without losing too much performance. (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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its 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 core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
