Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX Titan Black		250 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 50 Watts (20%)

Memory Bandwidth

In theory, the Radeon RX 6800 XT should be 56% faster than the GeForce GTX Titan Black overall, due to its higher data rate. (explain)

Radeon RX 6800 XT		524288 MB/sec
GeForce GTX Titan Black		336000 MB/sec
	Difference: 188288 (56%)

Texel Rate

The Radeon RX 6800 XT is much (more or less 146%) better at texture filtering than the GeForce GTX Titan Black. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce GTX Titan Black		213360 Mtexels/sec
	Difference: 312240 (146%)

Pixel Rate

The Radeon RX 6800 XT should be quite a bit (more or less 447%) more effective at anti-aliasing than the GeForce GTX Titan Black, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce GTX Titan Black		42672 Mpixels/sec
	Difference: 190928 (447%)

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 data (measured in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
