Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 680		195 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 105 Watts (54%)

Memory Bandwidth

In theory, the Radeon RX 6800 XT will be 173% quicker than the Geforce GTX 680 in general, because of its higher data rate. (explain)

Radeon RX 6800 XT		524288 MB/sec
Geforce GTX 680		192256 MB/sec
	Difference: 332032 (173%)

Texel Rate

The Radeon RX 6800 XT should be a lot (about 308%) faster with regards to anisotropic filtering than the Geforce GTX 680. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Geforce GTX 680		128768 Mtexels/sec
	Difference: 396832 (308%)

Pixel Rate

The Radeon RX 6800 XT is much (approximately 626%) more effective at full screen anti-aliasing than the Geforce GTX 680, and also should be capable of handling higher resolutions better. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 201408 (626%)

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 transported past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
