GeForce RTX 2070 vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which makes use of a 7 nm design. AMD has clocked the core speed at 1700 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this particular model. It features 3840 SPUs as well as 240 Texture Address Units 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 should be 14% quicker than the GeForce RTX 2070 overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 6800 should be a lot (approximately 101%) more effective 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

If using high levels of AA is important to you, then the Radeon RX 6800 is the winner, by a large margin. (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 (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
