GeForce RTX 2060 vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which has a GPU core clock speed of 1700 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also is made up of 3840 SPUs, 240 TAUs, and 96 ROPs.

GeForce RTX 2060		344064 MB/sec
	Difference: 180224 (52%)

Texel Rate

The Radeon RX 6800 will be quite a bit (more or less 149%) faster with regards to texture filtering than the GeForce RTX 2060. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 244200 (149%)

Pixel Rate

The Radeon RX 6800 is much (more or less 149%) better at FSAA than the GeForce RTX 2060, and capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 97680 (149%)

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 largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, 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 maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
