GeForce RTX 2080 SUPER vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which comes with 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 made up of 3840 SPUs, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon RX 6800 should in theory be just a bit better than the GeForce RTX 2080 SUPER overall. (explain)

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

Texel Rate

The Radeon RX 6800 will be a lot (approximately 29%) better at 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

If running with a high screen resolution is important to you, then the Radeon RX 6800 is the winner, by far. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus 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 bandwidth is, 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the 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 most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
