Radeon RX 6700 XT		393216 MB/sec
	Difference: 65536 (17%)

Texel Rate

The Radeon RX 6700 XT will be quite a bit (more or less 83%) more effective at AF than the GeForce RTX 2070. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 168320 (83%)

Pixel Rate

The Radeon RX 6700 XT will be a lot (approximately 65%) faster with regards to FSAA than the GeForce RTX 2070, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 58304 (65%)

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 (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends 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.
