Geforce GTX 1080 Ti vs Radeon RX 5700 XT

Intro

Compare all of that to the Radeon RX 5700 XT, which has GPU clock speed of 1605 MHz, and 8096 MB of GDDR6 RAM running at 1750 MHz through a 256-bit bus. It also is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT		225 Watts
Geforce GTX 1080 Ti		250 Watts
	Difference: 25 Watts (11%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 1080 Ti should be 8% faster than the Radeon RX 5700 XT overall, because of its higher bandwidth. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Radeon RX 5700 XT		458752 MB/sec
	Difference: 36864 (8%)

Texel Rate

The Geforce GTX 1080 Ti is a lot (about 29%) more effective at texture filtering than the Radeon RX 5700 XT. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 74720 (29%)

Pixel Rate

If using a high resolution is important to you, then the Geforce GTX 1080 Ti is a better choice, by far. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 27520 (27%)

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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core clock 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 most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
