Radeon RX 6800 vs Radeon RX 6950 XT

Intro

Compare all of that to the Radeon RX 6950 XT, which has a clock speed of 1925 MHz and a GDDR6 memory speed of 2250 MHz. It also features a 256-bit memory bus, and uses a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

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

Texel Rate

The Radeon RX 6950 XT should be much (approximately 51%) better at anisotropic filtering than the Radeon RX 6800. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon RX 6800		408000 Mtexels/sec
	Difference: 208000 (51%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6950 XT is a better choice, by far. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon RX 6800		163200 Mpixels/sec
	Difference: 83200 (51%)

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 (in units of MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
