GeForce RTX 3070		(Unknown) MB/sec
	Difference: 589824 (-100%)

Texel Rate

The Radeon RX 6950 XT should be much (more or less 123%) better at anisotropic filtering than the GeForce RTX 3070. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 340000 (123%)

Pixel Rate

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

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 102400 (71%)

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 data (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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