GeForce RTX 2060 vs Radeon R9 390 8G

Intro

Compare all that to the Radeon R9 390 8G, which has a core clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 512-bit bus, and makes use of a 28 nm design. It features 2560 SPUs, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
Radeon R9 390 8G		275 Watts
	Difference: 115 Watts (72%)

Memory Bandwidth

In theory, the Radeon R9 390 8G should be a little bit faster than the GeForce RTX 2060 overall. (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 just a bit (more or less 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

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2060 is the winner, though only just barely. (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 max amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that are 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
