GeForce RTX 3070 Ti vs Radeon RX 6900 XT

Intro

Compare those specifications 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 particular card. It features 5120 SPUs as well as 320 Texture Address Units and 128 ROPs.

GeForce RTX 3070 Ti		290 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 10 Watts (3%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3070 Ti will be 19% quicker than the Radeon RX 6900 XT in general, because of its higher data rate. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
Radeon RX 6900 XT		524288 MB/sec
	Difference: 98611 (19%)

Texel Rate

The Radeon RX 6900 XT should be quite a bit (approximately 93%) faster with regards to 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

If using a high resolution is important to you, then the Radeon RX 6900 XT is superior to the GeForce RTX 3070 Ti, by a large margin. (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 information (in units of megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
