Geforce GTX 1080 Ti vs Radeon RX 6700 XT

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6700 XT		230 Watts
Geforce GTX 1080 Ti		250 Watts
	Difference: 20 Watts (9%)

Memory Bandwidth

In theory, the Geforce GTX 1080 Ti will be 26% faster than the Radeon RX 6700 XT in general, because of its higher data rate. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Radeon RX 6700 XT		393216 MB/sec
	Difference: 102400 (26%)

Texel Rate

The Radeon RX 6700 XT will be a bit (more or less 12%) better at texture filtering than the Geforce GTX 1080 Ti. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Geforce GTX 1080 Ti		331520 Mtexels/sec
	Difference: 39840 (12%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6700 XT is a better choice, though only just barely. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Geforce GTX 1080 Ti		130240 Mpixels/sec
	Difference: 18304 (14%)

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 (counted in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's 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 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 reach the maximum fill rate.
