GeForce GTX 1080 vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which has a core clock frequency of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 128-bit memory bus, and uses a 7 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 6600 XT		160 Watts
GeForce GTX 1080		180 Watts
	Difference: 20 Watts (13%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1080 should perform much faster than the Radeon RX 6600 XT in general. (explain)

GeForce GTX 1080		327680 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 65536 (25%)

Texel Rate

The GeForce GTX 1080 should be a little bit (approximately 2%) faster with regards to AF than the Radeon RX 6600 XT. (explain)

GeForce GTX 1080		257120 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 5216 (2%)

Pixel Rate

The Radeon RX 6600 XT will be quite a bit (more or less 22%) more effective at full screen anti-aliasing than the GeForce GTX 1080, and also able to handle higher resolutions better. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 1080		102848 Mpixels/sec
	Difference: 23104 (22%)

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 (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
