GeForce GTX 1080 vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which comes with a GPU core clock speed of 1968 MHz, and 8192 MB of GDDR6 RAM running at 2000 MHz through a 128-bit bus. It also features 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

As far as performance goes, the GeForce GTX 1080 should in theory be much superior to 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 (more or less 2%) better at anisotropic filtering 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

If running with a high screen resolution is important to you, then the Radeon RX 6600 XT is superior to the GeForce GTX 1080, and very much so. (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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 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 AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
