GeForce RTX 3070 Ti vs Radeon RX 6800

Intro

The GeForce RTX 3070 Ti has a GPU core 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 made up of 6144 Stream Processors, 192 Texture Address Units, and 96 Raster Operation Units.

Compare that to the Radeon RX 6800, which comes with core speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 3840 SPUs as well as 240 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6800 250 Watts
GeForce RTX 3070 Ti 290 Watts
Difference: 40 Watts (16%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3070 Ti will be 19% faster than the Radeon RX 6800 in general, due to its higher data rate. (explain)

GeForce RTX 3070 Ti 622899 MB/sec
Radeon RX 6800 524288 MB/sec
Difference: 98611 (19%)

Texel Rate

The Radeon RX 6800 is quite a bit (more or less 35%) faster with regards to anisotropic 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 will be a bit (more or less 8%) better at AA than the GeForce RTX 3070 Ti, and should be able to handle higher resolutions without losing too much performance. (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 largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of 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.
