GeForce RTX 3080 Ti vs Radeon RX 6700 XT

Intro

Compare all that to the Radeon RX 6700 XT, which features a GPU core clock speed of 2321 MHz, and (Unknown) MB of GDDR6 memory running at 2000 MHz through a 192-bit bus. It also is comprised of 2560 Stream Processors, 160 TAUs, and 64 ROPs.

Radeon RX 6700 XT		393216 MB/sec
	Difference: 541081 (138%)

Texel Rate

The GeForce RTX 3080 Ti should be a little bit (approximately 18%) better at texture filtering than the Radeon RX 6700 XT. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 6700 XT		371360 Mtexels/sec
	Difference: 65440 (18%)

Pixel Rate

The GeForce RTX 3080 Ti is a small bit (about 3%) faster with regards to anti-aliasing than the Radeon RX 6700 XT, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 6700 XT		148544 Mpixels/sec
	Difference: 4336 (3%)

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 largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 ability to get to the max fill rate.
