GeForce RTX 2080 SUPER vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which features GPU clock speed of 1700 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 3840 SPUs, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800 should theoretically be a bit faster than the GeForce RTX 2080 SUPER in general. (explain)

Radeon RX 6800		524288 MB/sec
GeForce RTX 2080 SUPER		507904 MB/sec
	Difference: 16384 (3%)

Texel Rate

The Radeon RX 6800 should be a lot (about 29%) faster with regards to AF than the GeForce RTX 2080 SUPER. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 91200 (29%)

Pixel Rate

The Radeon RX 6800 will be much (approximately 55%) more effective at AA than the GeForce RTX 2080 SUPER, and also should be able to handle higher resolutions more effectively. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 57600 (55%)

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 largest amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
