GeForce RTX 2080 SUPER vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which makes use of a 7 nm design. AMD has clocked the core frequency at 1700 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this specific model. 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

The Radeon RX 6800 should in theory 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 is much (more or less 29%) more effective 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 using a high screen resolution is important to you, then the Radeon RX 6800 is the winner, by a large margin. (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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
