Geforce GTX 1080 Ti vs Radeon RX 5500 XT

Intro

Compare all of that to the Radeon RX 5500 XT, which makes use of a 7 nm design. AMD has set the core speed at 1717 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this specific card. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

	Difference: 266240 (116%)

Texel Rate

The Geforce GTX 1080 Ti will be much (about 119%) better at AF than the Radeon RX 5500 XT. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 180424 (119%)

Pixel Rate

The Geforce GTX 1080 Ti will be a lot (approximately 137%) more effective at anti-aliasing than the Radeon RX 5500 XT, and also able to handle higher screen resolutions without losing too much performance. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 75296 (137%)

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 information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
