GeForce RTX 2080 Ti vs GeForce RTX 3070 Ti

Intro

Compare that to the GeForce RTX 3070 Ti, which features a clock frequency of 1575 MHz and a GDDR6X memory speed of 1188 MHz. It also uses a 256-bit memory bus, and uses a 8 nm design. It features 6144 SPUs, 192 Texture Address Units, and 96 Raster Operation Units.

Memory Bandwidth

As far as performance goes, the GeForce RTX 2080 Ti should in theory be a bit superior to the GeForce RTX 3070 Ti in general. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
GeForce RTX 3070 Ti		622899 MB/sec
	Difference: 7885 (1%)

Texel Rate

The GeForce RTX 2080 Ti should be quite a bit (approximately 21%) more effective at texture filtering than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 64800 (21%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3070 Ti is a better choice, by a large margin. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 32400 (27%)

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 moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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 - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
