GeForce RTX 2060 vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which has GPU core speed of 1700 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also is comprised of 3840 Stream Processors, 240 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
Radeon RX 6800		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

In theory, the Radeon RX 6800 should be 52% quicker than the GeForce RTX 2060 overall, due to its greater bandwidth. (explain)

Radeon RX 6800		524288 MB/sec
GeForce RTX 2060		344064 MB/sec
	Difference: 180224 (52%)

Texel Rate

The Radeon RX 6800 is quite a bit (about 149%) more effective at AF than the GeForce RTX 2060. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 244200 (149%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6800 is the winner, by far. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 97680 (149%)

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 moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If 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 are applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling 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 could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
