GeForce RTX 3070 Ti		622899 MB/sec
	Difference: 111104 (18%)

Texel Rate

The GeForce RTX 4080 is quite a bit (about 122%) more effective at texture filtering than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 367920 (122%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 4080 is a better choice, by a large margin. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce RTX 3070 Ti		151200 Mpixels/sec
	Difference: 95760 (63%)

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 (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
