GeForce RTX 3070 Ti vs Radeon RX 6900 XT

Intro

Compare those specs to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM is set to run at a speed of 2000 MHz on this card. It features 5120 SPUs along with 320 Texture Address Units and 128 ROPs.

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

Texel Rate

The Radeon RX 6900 XT should be much (approximately 93%) faster with regards to anisotropic 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

If running with high levels of AA is important to you, then the Radeon RX 6900 XT is the winner, by far. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 the video card could possibly record to the 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 the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
