Radeon RX 6950 XT		335 Watts
	Difference: 50 Watts (18%)

Memory Bandwidth

In theory, the Radeon RX 6950 XT is 14% faster than the GeForce RTX 4070 Ti in general, because of its higher data rate. (explain)

Radeon RX 6950 XT		589824 MB/sec
GeForce RTX 4070 Ti		516096 MB/sec
	Difference: 73728 (14%)

Texel Rate

The Radeon RX 6950 XT will be a small bit (more or less 11%) better at anisotropic filtering than the GeForce RTX 4070 Ti. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce RTX 4070 Ti		554400 Mtexels/sec
	Difference: 61600 (11%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6950 XT is a better choice, by far. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce RTX 4070 Ti		184800 Mpixels/sec
	Difference: 61600 (33%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
