Performance-wise, the Radeon R9 390 8G should in theory be a little bit better than the GeForce RTX 2060 in general. (explain)

Radeon R9 390 8G		384000 MB/sec
GeForce RTX 2060		344064 MB/sec
	Difference: 39936 (12%)

Texel Rate

The GeForce RTX 2060 should be a bit (approximately 2%) better at AF than the Radeon R9 390 8G. (explain)

GeForce RTX 2060		163800 Mtexels/sec
Radeon R9 390 8G		160000 Mtexels/sec
	Difference: 3800 (2%)

Pixel Rate

The GeForce RTX 2060 will be just a bit (about 2%) faster with regards to full screen anti-aliasing than the Radeon R9 390 8G, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 2060		65520 Mpixels/sec
Radeon R9 390 8G		64000 Mpixels/sec
	Difference: 1520 (2%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
