Texel Rate

The GeForce RTX 4070 Ti is a lot (about 83%) better at anisotropic filtering than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 252000 (83%)

Pixel Rate

The GeForce RTX 4070 Ti will be quite a bit (more or less 22%) better at AA than the GeForce RTX 3070 Ti, and also able to handle higher screen resolutions while still performing well. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
GeForce RTX 3070 Ti		151200 Mpixels/sec
	Difference: 33600 (22%)

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 data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
