GeForce RTX 2070 vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which comes with GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 memory running at 2000 MHz through a 256-bit bus. It also features 5120 Stream Processors, 320 Texture Address Units, and 128 Raster Operation Units.

GeForce RTX 2070		175 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 125 Watts (71%)

Memory Bandwidth

Performance-wise, the Radeon RX 6900 XT should in theory be just a bit better than the GeForce RTX 2070 overall. (explain)

Radeon RX 6900 XT		524288 MB/sec
GeForce RTX 2070		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT is a lot (about 188%) better at texture filtering than the GeForce RTX 2070. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 380960 (188%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6900 XT is a better choice, and very much so. (explain)

Radeon RX 6900 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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
