GeForce RTX 3080 Ti vs Radeon RX 6750 XT

Intro

Compare those specifications to the Radeon RX 6750 XT, which features GPU clock speed of 2150 MHz, and 12288 MB of GDDR6 RAM running at 2250 MHz through a 192-bit bus. It also features 2560 Stream Processors, 160 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6750 XT		250 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti should be 111% quicker than the Radeon RX 6750 XT in general, due to its higher bandwidth. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 491929 (111%)

Texel Rate

The GeForce RTX 3080 Ti should be much (more or less 27%) more effective at texture filtering than the Radeon RX 6750 XT. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 6750 XT		344000 Mtexels/sec
	Difference: 92800 (27%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3080 Ti is a better choice, but only just. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 15280 (11%)

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 max amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling 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 the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
