GeForce RTX 3070 Ti vs Radeon RX 6900 XT

Intro

Compare all that to the Radeon RX 6900 XT, which has a GPU core clock speed of 1825 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is made up of 5120 Stream Processors, 320 Texture Address Units, and 128 Raster Operation Units.

GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 281600 (93%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6900 XT is superior to the GeForce RTX 3070 Ti, and very much so. (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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
