GeForce RTX 3070 Ti vs Radeon RX 6800

Intro

The GeForce RTX 3070 Ti uses a 8 nm design. nVidia has clocked the core frequency at 1575 MHz. The GDDR6X RAM runs at a speed of 1188 MHz on this particular card. It features 6144 SPUs as well as 192 TAUs and 96 ROPs.

Compare all that to the Radeon RX 6800, which has core clock speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 3840 SPUs along with 240 TAUs and 96 ROPs.

The Radeon RX 6800 is quite a bit (approximately 35%) better at texture filtering than the GeForce RTX 3070 Ti. (explain)

Radeon RX 6800 408000 Mtexels/sec
GeForce RTX 3070 Ti 302400 Mtexels/sec
Difference: 105600 (35%)

Pixel Rate

The Radeon RX 6800 should be a little bit (approximately 8%) better at AA than the GeForce RTX 3070 Ti, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6800 163200 Mpixels/sec
GeForce RTX 3070 Ti 151200 Mpixels/sec
Difference: 12000 (8%)

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 max amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling 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 that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
