GeForce RTX 2060 Super vs Radeon RX 6900 XT

Intro

Compare all that to the Radeon RX 6900 XT, which comes with a clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It features 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

GeForce RTX 2060 Super		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT should be a lot (approximately 192%) more effective at texture filtering than the GeForce RTX 2060 Super. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 2060 Super		199920 Mtexels/sec
	Difference: 384080 (192%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6900 XT is the winner, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce RTX 2060 Super		94080 Mpixels/sec
	Difference: 139520 (148%)

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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 are applied in one second. This is worked out by multiplying the total texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
