GeForce GTX 1080 vs Radeon RX 6700 XT

Intro

The GeForce GTX 1080 comes with a GPU core clock speed of 1607 MHz, and the 8192 MB of GDDR5X RAM is set to run at 1251 MHz through a 256-bit bus. It also is made up of 2560 Stream Processors, 160 Texture Address Units, and 64 Raster Operation Units.

Compare all of that to the Radeon RX 6700 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 2321 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this particular model. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

GeForce GTX 1080 327680 MB/sec
Difference: 65536 (20%)

Texel Rate

The Radeon RX 6700 XT will be a lot (more or less 44%) faster with regards to anisotropic filtering than the GeForce GTX 1080. (explain)

Radeon RX 6700 XT 371360 Mtexels/sec
GeForce GTX 1080 257120 Mtexels/sec
Difference: 114240 (44%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6700 XT is the winner, and very much so. (explain)

Radeon RX 6700 XT 148544 Mpixels/sec
GeForce GTX 1080 102848 Mpixels/sec
Difference: 45696 (44%)

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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
