GeForce RTX 2080 SUPER vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which has core speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 3840 SPUs as well as 240 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 should be a small 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 is quite a bit (about 29%) more effective at texture filtering 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 should be quite a bit (approximately 55%) better at anti-aliasing than the GeForce RTX 2080 SUPER, and also will be able to handle higher screen resolutions without losing too much performance. (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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher 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 that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
