GeForce RTX 3070		(Unknown) MB/sec
	Difference: 819200 (-100%)

Texel Rate

The Radeon RX 7900 XT will be a lot (more or less 83%) better at AF than the GeForce RTX 3070. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 228000 (83%)

Pixel Rate

The Radeon RX 7900 XT is a lot (about 100%) more effective at AA than the GeForce RTX 3070, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 144000 (100%)

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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 applied in one second. This number 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 video card will be at handling 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 could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
