GeForce RTX 2070		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT should be a lot (approximately 188%) better at texture filtering than the GeForce RTX 2070. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 380960 (188%)

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 2070		90240 Mpixels/sec
	Difference: 143360 (159%)

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 max amount of information (in units of MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
