Geforce GTX 1080 Ti vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which comes with clock speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 memory. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
Geforce GTX 1080 Ti		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the Geforce GTX 1080 Ti will be 116% faster than the Radeon RX 5500 in general, due to its greater bandwidth. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 266240 (116%)

Texel Rate

The Geforce GTX 1080 Ti is a lot (approximately 126%) more effective at AF than the Radeon RX 5500. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 184560 (126%)

Pixel Rate

The Geforce GTX 1080 Ti should be much (more or less 144%) better at AA than the Radeon RX 5500, and also able to handle higher screen resolutions while still performing well. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 76800 (144%)

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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour 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 rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
