GeForce GTX 970		224000 MB/sec
	Difference: 759040 (339%)

Texel Rate

The Radeon RX 7900 XTX should be much (more or less 552%) more effective at anisotropic filtering than the GeForce GTX 970. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 603120 (552%)

Pixel Rate

The Radeon RX 7900 XTX is quite a bit (approximately 430%) faster with regards to AA than the GeForce GTX 970, and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 288960 (430%)

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 largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
