The Radeon RX 6950 XT is a little bit (about 5%) more effective at anisotropic filtering than the Radeon RX 6900 XT. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon RX 6900 XT		584000 Mtexels/sec
	Difference: 32000 (5%)

Pixel Rate

The Radeon RX 6950 XT is a small bit (more or less 5%) better at anti-aliasing than the Radeon RX 6900 XT, and also should be able to handle higher resolutions better. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon RX 6900 XT		233600 Mpixels/sec
	Difference: 12800 (5%)

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 data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 per second. This number is worked out by multiplying the total texture units by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
