GeForce RTX 2070 vs Radeon RX 6800 XT

Intro

Compare those specs to the Radeon RX 6800 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM runs at a frequency of 2000 MHz on this specific model. It features 4608 SPUs along with 288 TAUs and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070		175 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 125 Watts (71%)

Memory Bandwidth

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

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

Texel Rate

The Radeon RX 6800 XT is a lot (approximately 159%) faster with regards to texture filtering than the GeForce RTX 2070. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 322560 (159%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is superior to the GeForce RTX 2070, and very much so. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 143360 (159%)

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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
