GeForce RTX 3060 vs Radeon R9 390 8G

Intro

Compare that to the Radeon R9 390 8G, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM works at a speed of 1500 MHz on this particular card. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The Radeon R9 390 8G should in theory perform a little bit faster than the GeForce RTX 3060 in general. (explain)

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

Texel Rate

The Radeon R9 390 8G is a bit (about 8%) more effective at texture filtering than the GeForce RTX 3060. (explain)

Radeon R9 390 8G		160000 Mtexels/sec
GeForce RTX 3060		147840 Mtexels/sec
	Difference: 12160 (8%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 390 8G is superior to the GeForce RTX 3060, but not by far. (explain)

Radeon R9 390 8G		64000 Mpixels/sec
GeForce RTX 3060		63360 Mpixels/sec
	Difference: 640 (1%)

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 max amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
