The GeForce RTX 3070 Ti is quite a bit (approximately 44%) more effective at AF than the GeForce GTX 780 Ti. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
GeForce GTX 780 Ti		210000 Mtexels/sec
	Difference: 92400 (44%)

Pixel Rate

The GeForce RTX 3070 Ti is quite a bit (more or less 260%) more effective at AA than the GeForce GTX 780 Ti, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 109200 (260%)

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 information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. 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 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.
