GeForce RTX 4070 Ti		516096 MB/sec
	Difference: 8192 (2%)

Texel Rate

The GeForce RTX 4070 Ti is a small bit (more or less 5%) better at AF 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 a lot (about 26%) faster with regards to FSAA than the GeForce RTX 4070 Ti, and able to handle higher resolutions more effectively. (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 max amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 potential to reach the maximum fill rate.
