GeForce RTX 2080 Ti vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this particular card. It features 5120 SPUs along with 320 Texture Address Units and 128 Rasterization Operator Units.

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 2080 Ti		367200 Mtexels/sec
	Difference: 216800 (59%)

Pixel Rate

The Radeon RX 6900 XT will be quite a bit (about 97%) faster with regards to FSAA than the GeForce RTX 2080 Ti, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 114800 (97%)

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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at 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 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
