GeForce RTX 2070 vs Radeon RX 6900 XT

Intro

The GeForce RTX 2070 comes with a core clock speed of 1410 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit memory bus, and uses a 12 nm design. It features 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Compare that to the Radeon RX 6900 XT, which features a clock frequency of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit bus, and makes use of a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

Texel Rate

The Radeon RX 6900 XT is a lot (more or less 188%) more effective at AF 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 lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is superior to the GeForce RTX 2070, by far. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
