GeForce RTX 2080 vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which features a clock speed of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 Texture Address Units, and 96 Raster Operation Units.

Texel Rate

The Radeon RX 6800 will be much (more or less 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

The Radeon RX 6800 will be quite a bit (approximately 68%) more effective at AA than the GeForce RTX 2080, and also will be capable of handling higher screen resolutions while still performing well. (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 largest amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once 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 are processed per second. This figure is worked out by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card 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 number of Raster Operations Pipelines by the the core clock speed. 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
