GeForce RTX 2080 Ti vs GeForce RTX 3070 Ti

Intro

Compare those specifications to the GeForce RTX 3070 Ti, which uses a 8 nm design. nVidia has set the core frequency at 1575 MHz. The GDDR6X memory runs at a frequency of 1188 MHz on this particular model. It features 6144 SPUs as well as 192 Texture Address Units and 96 ROPs.

GeForce RTX 2080 Ti		250 Watts
GeForce RTX 3070 Ti		290 Watts
	Difference: 40 Watts (16%)

Memory Bandwidth

In theory, the GeForce RTX 2080 Ti will be 1% quicker than the GeForce RTX 3070 Ti overall, due to its greater bandwidth. (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 is a lot (more or less 21%) better at anisotropic 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

The GeForce RTX 3070 Ti will be quite a bit (more or less 27%) better at full screen anti-aliasing than the GeForce RTX 2080 Ti, and also will be capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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