GeForce RTX 2070 vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which comes with a core clock frequency of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 96 ROPs.

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

Memory Bandwidth

The Radeon RX 6800, in theory, should be just a bit faster than the GeForce RTX 2070 in general. (explain)

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

Texel Rate

The Radeon RX 6800 is much (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

If running with a high resolution is important to you, then the Radeon RX 6800 is a better choice, and very much so. (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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 bandwidth is, the lower the ability to reach the max fill rate.
