Texel Rate

The GeForce RTX 4070 Ti will be a little 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 is quite a bit (more or less 26%) faster with regards to full screen anti-aliasing than the GeForce RTX 4070 Ti, and will be capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
