Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce RTX 3080 12 GB should in theory perform a bit faster than the GeForce RTX 3080 Ti in general. (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 should be quite a bit (more or less 24%) more effective at AF 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

The GeForce RTX 3080 Ti should be a small bit (about 8%) more effective at AA than the GeForce RTX 3080 12 GB, and will be capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface in one second. The number 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 ANOTHER 2x. The better the card's memory bandwidth, 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 applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
