GeForce GTX 780 Ti vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which has core clock speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.

Radeon RX 5500 XT		229376 MB/sec
	Difference: 106624 (46%)

Texel Rate

The GeForce GTX 780 Ti is a lot (more or less 39%) better at anisotropic filtering than the Radeon RX 5500 XT. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 58904 (39%)

Pixel Rate

The Radeon RX 5500 XT is much (about 31%) faster with regards to anti-aliasing than the GeForce GTX 780 Ti, and should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 12944 (31%)

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 largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount 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 clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
