GeForce RTX 2080 vs Radeon RX 6700 XT

Intro

The GeForce RTX 2080 has a clock speed of 1515 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 is made up of 2944 SPUs, 184 TAUs, and 64 Raster Operation Units.

Compare those specifications to the Radeon RX 6700 XT, which comes with clock speeds of 2321 MHz on the GPU, and 2000 MHz on the (Unknown) MB of GDDR6 memory. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Radeon RX 6700 XT 393216 MB/sec
Difference: 65536 (17%)

Texel Rate

The Radeon RX 6700 XT will be much (more or less 33%) faster with regards to texture filtering than the GeForce RTX 2080. (explain)

Radeon RX 6700 XT 371360 Mtexels/sec
GeForce RTX 2080 278760 Mtexels/sec
Difference: 92600 (33%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6700 XT is superior to the GeForce RTX 2080, and very much so. (explain)

Radeon RX 6700 XT 148544 Mpixels/sec
GeForce RTX 2080 96960 Mpixels/sec
Difference: 51584 (53%)

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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core 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 most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
