GeForce RTX 3070 Ti vs Radeon RX 6900 XT

Intro

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

Compare all of that to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has clocked the core speed at 1825 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this particular model. It features 5120 SPUs as well as 320 TAUs and 128 Rasterization Operator Units.

Radeon RX 6900 XT 524288 MB/sec
Difference: 98611 (19%)

Texel Rate

The Radeon RX 6900 XT will be much (approximately 93%) more effective at texture filtering than the GeForce RTX 3070 Ti. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
GeForce RTX 3070 Ti 302400 Mtexels/sec
Difference: 281600 (93%)

Pixel Rate

The Radeon RX 6900 XT should be a lot (more or less 54%) faster with regards to AA than the GeForce RTX 3070 Ti, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6900 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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units 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 can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
