GeForce RTX 3070 Ti vs Radeon RX 6800 XT

Intro

The GeForce RTX 3070 Ti comes with a GPU core clock speed of 1575 MHz, and the 8192 MB of GDDR6X memory is set to run at 1188 MHz through a 256-bit bus. It also is comprised of 6144 SPUs, 192 Texture Address Units, and 96 Raster Operation Units.

Compare all that to the Radeon RX 6800 XT, which features GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also is comprised of 4608 Stream Processors, 288 Texture Address Units, and 128 ROPs.

Radeon RX 6800 XT 524288 MB/sec
Difference: 98611 (19%)

Texel Rate

The Radeon RX 6800 XT will be a lot (more or less 74%) faster with regards to AF than the GeForce RTX 3070 Ti. (explain)

Radeon RX 6800 XT 525600 Mtexels/sec
GeForce RTX 3070 Ti 302400 Mtexels/sec
Difference: 223200 (74%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6800 XT is the winner, and very much so. (explain)

Radeon RX 6800 XT 233600 Mpixels/sec
GeForce RTX 3070 Ti 151200 Mpixels/sec
Difference: 82400 (54%)

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 data (in units of megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
