GeForce RTX 2070 vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which comes with GPU core 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 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

GeForce RTX 2070		175 Watts
Radeon RX 6800		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 is 14% faster than the GeForce RTX 2070 in general, because of its greater bandwidth. (explain)

Radeon RX 6800		524288 MB/sec
GeForce RTX 2070		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6800 will be a lot (more or less 101%) more effective at AF than the GeForce RTX 2070. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 204960 (101%)

Pixel Rate

The Radeon RX 6800 is a lot (approximately 81%) better at full screen anti-aliasing than the GeForce RTX 2070, and will be capable of handling higher resolutions more effectively. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 72960 (81%)

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 max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
