Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070 Ti		290 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 60 Watts (21%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 3080 Ti should in theory be quite a bit better than the GeForce RTX 3070 Ti in general. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce RTX 3070 Ti		622899 MB/sec
	Difference: 311398 (50%)

Texel Rate

The GeForce RTX 3080 Ti is much (more or less 44%) more effective at anisotropic filtering than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 134400 (44%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3080 Ti is a better choice, not by a very large margin though. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 3070 Ti		151200 Mpixels/sec
	Difference: 1680 (1%)

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 (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of 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.
