GeForce RTX 2080 SUPER vs Radeon RX 6800

Intro

Compare that to the Radeon RX 6800, which comes with a core clock frequency of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It features 3840 SPUs, 240 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon RX 6800 should in theory be a bit superior to 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 is quite a bit (about 29%) faster with regards to anisotropic 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 a lot (about 55%) more effective at AA than the GeForce RTX 2080 SUPER, and should be capable of handling higher screen resolutions without slowing down too much. (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 information (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
