GeForce RTX 3070 Ti vs Radeon RX 6800 XT

Intro

The GeForce RTX 3070 Ti has a GPU 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 features 6144 SPUs, 192 Texture Address Units, and 96 Raster Operation Units.

Compare those specifications to the Radeon RX 6800 XT, which comes with core speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 4608 SPUs as well as 288 TAUs and 128 Rasterization Operator Units.

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

Texel Rate

The Radeon RX 6800 XT is much (about 74%) more effective at anisotropic filtering 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 high levels of AA is important to you, then the Radeon RX 6800 XT is superior to the GeForce RTX 3070 Ti, by far. (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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 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 maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
