GeForce RTX 3070 Ti vs GeForce RTX 3080

Intro

Compare that to the GeForce RTX 3080, which comes with a core clock frequency of 1440 MHz and a GDDR6X memory frequency of 1188 MHz. It also uses a 320-bit memory bus, and uses a 8 nm design. It is made up of 8704 SPUs, 272 Texture Address Units, and 96 ROPs.

Texel Rate

The GeForce RTX 3080 will be much (approximately 30%) better at AF than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 89280 (30%)

Pixel Rate

The GeForce RTX 3070 Ti should be a little bit (more or less 9%) faster with regards to full screen anti-aliasing than the GeForce RTX 3080, and capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
GeForce RTX 3080		138240 Mpixels/sec
	Difference: 12960 (9%)

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 (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
