GeForce RTX 2080 SUPER		507904 MB/sec
	Difference: 8192 (2%)

Texel Rate

The GeForce RTX 4070 Ti should be quite a bit (more or less 75%) more effective at anisotropic filtering than the GeForce RTX 2080 SUPER. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 237600 (75%)

Pixel Rate

The GeForce RTX 4070 Ti is quite a bit (approximately 75%) better at FSAA than the GeForce RTX 2080 SUPER, and able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 79200 (75%)

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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
