In theory, the Radeon R9 390 8G is 12% quicker than the GeForce RTX 2060 in general, because of its greater data rate. (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 little bit (approximately 2%) more effective at anisotropic filtering 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 is a little bit (more or less 2%) more effective at FSAA than the Radeon R9 390 8G, and also will be capable of handling higher screen resolutions better. (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 information (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
