	Difference: 20480 (4%)

Texel Rate

The GeForce RTX 4070 Ti is much (more or less 67%) more effective at AF than the Geforce GTX 1080 Ti. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Geforce GTX 1080 Ti		331520 Mtexels/sec
	Difference: 222880 (67%)

Pixel Rate

The GeForce RTX 4070 Ti will be quite a bit (approximately 42%) faster with regards to FSAA than the Geforce GTX 1080 Ti, and will be capable of handling higher resolutions better. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Geforce GTX 1080 Ti		130240 Mpixels/sec
	Difference: 54560 (42%)

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 MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 applied in one second. This is worked out by multiplying the total texture units of the card by the core 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 number of pixels that the graphics chip can possibly record 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 clock 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
