GeForce GTX 1080 vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which features GPU core speed of 1968 MHz, and 8192 MB of GDDR6 memory set to run at 2000 MHz through a 128-bit bus. It also features 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

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

Theoretically speaking, the GeForce GTX 1080 is 25% faster than the Radeon RX 6600 XT overall, because of its higher bandwidth. (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 bit (about 2%) more effective at texture 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

The Radeon RX 6600 XT is quite a bit (more or less 22%) faster with regards to FSAA than the GeForce GTX 1080, and should be capable of handling higher screen resolutions while still performing well. (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 largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
