GeForce GTX 1070		150 Watts
Radeon RX 6800		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the Radeon RX 6800 is 100% faster than the GeForce GTX 1070 in general, because of its higher data rate. (explain)

Radeon RX 6800		524288 MB/sec
GeForce GTX 1070		262144 MB/sec
	Difference: 262144 (100%)

Texel Rate

The Radeon RX 6800 will be a lot (about 126%) faster with regards to texture filtering than the GeForce GTX 1070. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce GTX 1070		180720 Mtexels/sec
	Difference: 227280 (126%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6800 is the winner, and very much so. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce GTX 1070		96384 Mpixels/sec
	Difference: 66816 (69%)

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 megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
