Texel Rate

The Radeon RX 7900 XTX will be quite a bit (approximately 251%) more effective at texture filtering than the GeForce RTX 2070. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 509280 (251%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 7900 XTX is superior to the GeForce RTX 2070, by a large margin. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 265920 (295%)

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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
