GeForce RTX 3060		170 Watts
Radeon R9 390X 8G		275 Watts
	Difference: 105 Watts (62%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 390X 8G is 4% quicker than the GeForce RTX 3060 in general, due to its greater bandwidth. (explain)

Radeon R9 390X 8G		384000 MB/sec
GeForce RTX 3060		368640 MB/sec
	Difference: 15360 (4%)

Texel Rate

The Radeon R9 390X 8G will be quite a bit (approximately 25%) better at anisotropic filtering than the GeForce RTX 3060. (explain)

Radeon R9 390X 8G		184800 Mtexels/sec
GeForce RTX 3060		147840 Mtexels/sec
	Difference: 36960 (25%)

Pixel Rate

The Radeon R9 390X 8G should be a little bit (about 6%) better at AA than the GeForce RTX 3060, and will be able to handle higher resolutions better. (explain)

Radeon R9 390X 8G		67200 Mpixels/sec
GeForce RTX 3060		63360 Mpixels/sec
	Difference: 3840 (6%)

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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
