GeForce GTX 1070 Ti vs Radeon RX 6900 XT

Intro

Compare all that to the Radeon RX 6900 XT, which has core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 5120 SPUs along with 320 Texture Address Units and 128 Rasterization Operator Units.

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce GTX 1070 Ti		244264 Mtexels/sec
	Difference: 339736 (139%)

Pixel Rate

The Radeon RX 6900 XT will be a lot (about 127%) better at anti-aliasing than the GeForce GTX 1070 Ti, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce GTX 1070 Ti		102848 Mpixels/sec
	Difference: 130752 (127%)

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 information (measured in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core clock 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 the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
