GeForce RTX 2070 Super vs Radeon RX 6900 XT

Intro

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

	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT should be a lot (approximately 127%) better at texture filtering than the GeForce RTX 2070 Super. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 327200 (127%)

Pixel Rate

The Radeon RX 6900 XT should be a lot (approximately 127%) better at anti-aliasing than the GeForce RTX 2070 Super, and also able to handle higher resolutions more effectively. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce RTX 2070 Super		102720 Mpixels/sec
	Difference: 130880 (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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
