Geforce GTX 1080 Ti vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which comes with a core clock speed of 1968 MHz and a GDDR6 memory speed of 2000 MHz. It also features a 128-bit memory bus, and uses a 7 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
Geforce GTX 1080 Ti		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

The Geforce GTX 1080 Ti, in theory, should be quite a bit faster than the Radeon RX 6600 XT in general. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 233472 (89%)

Texel Rate

The Geforce GTX 1080 Ti should be a lot (about 32%) better at anisotropic filtering than the Radeon RX 6600 XT. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 79616 (32%)

Pixel Rate

If using high levels of AA is important to you, then the Geforce GTX 1080 Ti is superior to the Radeon RX 6600 XT, but it probably won't make a huge difference. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 6600 XT		125952 Mpixels/sec
	Difference: 4288 (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 data (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
