Geforce GTX 780		288384 MB/sec
	Difference: 334515 (116%)

Texel Rate

The GeForce RTX 3070 Ti is a lot (more or less 83%) more effective at texture filtering than the Geforce GTX 780. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 136704 (83%)

Pixel Rate

The GeForce RTX 3070 Ti is a lot (about 265%) faster with regards to FSAA than the Geforce GTX 780, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 109776 (265%)

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 largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, 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 worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 ability to get to the maximum fill rate.
