Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 4070 Ti		285 Watts
GeForce RTX 3080		320 Watts
	Difference: 35 Watts (12%)

Memory Bandwidth

The GeForce RTX 3080, in theory, should perform quite a bit faster than the GeForce RTX 4070 Ti overall. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce RTX 4070 Ti		516096 MB/sec
	Difference: 262451 (51%)

Texel Rate

The GeForce RTX 4070 Ti should be quite a bit (approximately 42%) more effective at anisotropic filtering than the GeForce RTX 3080. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
GeForce RTX 3080		391680 Mtexels/sec
	Difference: 162720 (42%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 4070 Ti is superior to the GeForce RTX 3080, and very much so. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
GeForce RTX 3080		138240 Mpixels/sec
	Difference: 46560 (34%)

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 information (measured in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once 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 anti-aliasing, 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 number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
