Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon R9 Nano should theoretically perform a bit faster than the GeForce RTX 2070 in general. (explain)

Radeon R9 Nano		512000 MB/sec
GeForce RTX 2070		458752 MB/sec
	Difference: 53248 (12%)

Texel Rate

The Radeon R9 Nano should be much (about 26%) better at anisotropic filtering than the GeForce RTX 2070. (explain)

GeForce RTX 2070		203040 Mtexels/sec
	Difference: 52960 (26%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 2070 is superior to the Radeon R9 Nano, and very much so. (explain)

GeForce RTX 2070		90240 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 26240 (41%)

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 data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
