Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 Ti		250 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 35 Watts (14%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 Ti should be 22% faster than the GeForce RTX 4070 Ti overall, due to its greater bandwidth. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
GeForce RTX 4070 Ti		516096 MB/sec
	Difference: 114688 (22%)

Texel Rate

The GeForce RTX 4070 Ti will be quite a bit (about 51%) more effective at AF than the GeForce RTX 2080 Ti. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
GeForce RTX 2080 Ti		367200 Mtexels/sec
	Difference: 187200 (51%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 4070 Ti is superior to the GeForce RTX 2080 Ti, by a large margin. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 66000 (56%)

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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
