The Radeon RX 7900 XT is much (approximately 83%) better at texture filtering 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 much (more or less 100%) faster with regards to anti-aliasing than the GeForce RTX 3070, and will be able to handle higher screen resolutions more effectively. (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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
