Geforce GTX 1080 Ti vs Radeon RX 6900 XT

Intro

Compare those specs to the Radeon RX 6900 XT, which features GPU core speed of 1825 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 5120 Stream Processors, 320 Texture Address Units, and 128 Raster Operation Units.

	Difference: 28672 (6%)

Texel Rate

The Radeon RX 6900 XT is a lot (more or less 76%) faster with regards to AF 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 is much (more or less 79%) faster with regards to full screen anti-aliasing than the Geforce GTX 1080 Ti, and will be capable of handling 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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
