The GeForce RTX 4070 Ti will be a bit (more or less 5%) more effective at texture filtering than the Radeon RX 6800 XT. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX 6800 XT		525600 Mtexels/sec
	Difference: 28800 (5%)

Pixel Rate

The Radeon RX 6800 XT should be quite a bit (about 26%) more effective at anti-aliasing than the GeForce RTX 4070 Ti, and will be able to handle higher resolutions while still performing well. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 4070 Ti		184800 Mpixels/sec
	Difference: 48800 (26%)

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 (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock 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 most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
