GeForce RTX 3070 Ti vs Radeon RX 6800 XT

Intro

Compare those specs to the Radeon RX 6800 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this particular model. It features 4608 SPUs along with 288 TAUs and 128 Rasterization Operator Units.

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

Texel Rate

The Radeon RX 6800 XT should be much (about 74%) more effective at texture 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 using a high screen resolution is important to you, then the Radeon RX 6800 XT is the winner, by a large margin. (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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
