Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070		220 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 80 Watts (36%)

Memory Bandwidth

The Radeon RX 6800 XT should in theory perform a little bit faster than the GeForce RTX 3070 overall. (explain)

Radeon RX 6800 XT		524288 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 524288 (-100%)

Texel Rate

The Radeon RX 6800 XT is much (about 90%) more effective at anisotropic filtering than the GeForce RTX 3070. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 249600 (90%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is superior to the GeForce RTX 3070, by a large margin. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 89600 (62%)

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 (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 processed in one second. This number is worked out by multiplying the total amount of texture units 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 that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
