GeForce RTX 2080 vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which makes use of a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this model. It features 3840 SPUs as well as 240 Texture Address Units and 96 Rasterization Operator Units.

GeForce RTX 2080		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6800 will be quite a bit (approximately 46%) faster with regards to AF than the GeForce RTX 2080. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 129240 (46%)

Pixel Rate

If using 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		96960 Mpixels/sec
	Difference: 66240 (68%)

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 (counted in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
