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

Theoretically speaking, the GeForce RTX 3080 Ti should be much faster 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 should be a lot (approximately 44%) faster with regards to texture 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

The GeForce RTX 3080 Ti should be a small bit (more or less 1%) more effective at FSAA than the GeForce RTX 3070 Ti, and also will be able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at 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 the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
