GeForce RTX 2070 Super vs Radeon RX 6900 XT

Intro

The GeForce RTX 2070 Super comes with a core clock speed of 1605 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It features 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1825 MHz. The GDDR6 memory works at a speed of 2000 MHz on this particular card. It features 5120 SPUs as well as 320 Texture Address Units and 128 ROPs.

GeForce RTX 2070 Super 215 Watts
Radeon RX 6900 XT 300 Watts
Difference: 85 Watts (40%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6900 XT should perform a little bit faster than the GeForce RTX 2070 Super overall. (explain)

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

Texel Rate

The Radeon RX 6900 XT will be much (about 127%) faster with regards to anisotropic filtering than the GeForce RTX 2070 Super. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
GeForce RTX 2070 Super 256800 Mtexels/sec
Difference: 327200 (127%)

Pixel Rate

The Radeon RX 6900 XT should be quite a bit (more or less 127%) more effective at full screen anti-aliasing than the GeForce RTX 2070 Super, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
GeForce RTX 2070 Super 102720 Mpixels/sec
Difference: 130880 (127%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
