Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 Ti		250 Watts
GeForce RTX 3090		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

In theory, the GeForce RTX 3090 will be 52% faster than the GeForce RTX 2080 Ti in general, due to its greater bandwidth. (explain)

GeForce RTX 3090		958668 MB/sec
GeForce RTX 2080 Ti		630784 MB/sec
	Difference: 327884 (52%)

Texel Rate

The GeForce RTX 3090 should be quite a bit (approximately 25%) better at texture filtering than the GeForce RTX 2080 Ti. (explain)

GeForce RTX 3090		457560 Mtexels/sec
GeForce RTX 2080 Ti		367200 Mtexels/sec
	Difference: 90360 (25%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3090 is the winner, by far. (explain)

GeForce RTX 3090		156240 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 37440 (32%)

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 (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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