Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon RX 6800 should theoretically be just a bit superior to the Radeon RX 6750 XT overall. (explain)

Radeon RX 6800		524288 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 81920 (19%)

Texel Rate

The Radeon RX 6800 should be just a bit (more or less 19%) more effective at AF than the Radeon RX 6750 XT. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 6750 XT		344000 Mtexels/sec
	Difference: 64000 (19%)

Pixel Rate

The Radeon RX 6800 will be a small bit (approximately 19%) faster with regards to anti-aliasing than the Radeon RX 6750 XT, and also should be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 25600 (19%)

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 largest amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
