Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 12 GB is 0% quicker than the GeForce RTX 3080 Ti overall, due to its higher data rate. (explain)

GeForce RTX 3080 12 GB		934298 MB/sec
GeForce RTX 3080 Ti		934297 MB/sec
	Difference: 1 (0%)

Texel Rate

The GeForce RTX 3080 Ti is quite a bit (approximately 24%) more effective at texture filtering than the GeForce RTX 3080 12 GB. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 3080 12 GB		352800 Mtexels/sec
	Difference: 84000 (24%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce RTX 3080 12 GB, though not by far. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 3080 12 GB		141120 Mpixels/sec
	Difference: 11760 (8%)

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 largest amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
