GeForce GTX 1080 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which comes with GPU clock speed of 2200 MHz, and 4096 MB of GDDR6 RAM running at 2250 MHz through a 64-bit bus. It also features 1024 Stream Processors, 64 TAUs, and 32 ROPs.

Radeon RX 6500 XT		107 Watts
GeForce GTX 1080		180 Watts
	Difference: 73 Watts (68%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 1080 should theoretically be quite a bit superior to the Radeon RX 6500 XT in general. (explain)

GeForce GTX 1080		327680 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 180224 (122%)

Texel Rate

The GeForce GTX 1080 should be much (more or less 83%) more effective at texture filtering than the Radeon RX 6500 XT. (explain)

GeForce GTX 1080		257120 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 116320 (83%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1080 is a better choice, by a large margin. (explain)

GeForce GTX 1080		102848 Mpixels/sec
Radeon RX 6500 XT		70400 Mpixels/sec
	Difference: 32448 (46%)

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 (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
