GeForce GTX 1080 vs Radeon RX 6700 XT

Intro

The GeForce GTX 1080 uses a 16 nm design. nVidia has set the core speed at 1607 MHz. The GDDR5X memory is set to run at a frequency of 1251 MHz on this specific card. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Compare those specs to the Radeon RX 6700 XT, which has GPU core speed of 2321 MHz, and (Unknown) MB of GDDR6 memory running at 2000 MHz through a 192-bit bus. It also features 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

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

Pixel Rate

The Radeon RX 6700 XT should be a lot (more or less 44%) better at full screen anti-aliasing than the GeForce GTX 1080, and capable of handling higher screen resolutions better. (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 maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
