In theory, the Radeon RX 6950 XT should be 13% quicker than the Radeon RX 6800 XT in general, due to its higher bandwidth. (explain)

Radeon RX 6950 XT		589824 MB/sec
Radeon RX 6800 XT		524288 MB/sec
	Difference: 65536 (13%)

Texel Rate

The Radeon RX 6950 XT will be a small bit (more or less 17%) faster with regards to AF than the Radeon RX 6800 XT. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon RX 6800 XT		525600 Mtexels/sec
	Difference: 90400 (17%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6950 XT is a better choice, but only just. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon RX 6800 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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record 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 card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
