GeForce RTX 2070 vs Radeon RX 6800

Intro

Compare those specs to the Radeon RX 6800, which has core clock speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 3840 SPUs as well as 240 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 will be 14% faster than the GeForce RTX 2070 in general, because of its higher 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 (approximately 101%) better at texture filtering 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 should be quite a bit (more or less 81%) faster with regards to full screen anti-aliasing than the GeForce RTX 2070, and also will be able to handle higher resolutions without slowing down too much. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
