Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Geforce GTX 680		195 Watts
	Difference: 65 Watts (50%)

Memory Bandwidth

In theory, the Radeon RX 5500 XT is 19% quicker than the Geforce GTX 680 in general, due to its greater data rate. (explain)

Radeon RX 5500 XT		229376 MB/sec
Geforce GTX 680		192256 MB/sec
	Difference: 37120 (19%)

Texel Rate

The Radeon RX 5500 XT should be a little bit (about 17%) faster with regards to anisotropic filtering than the Geforce GTX 680. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Geforce GTX 680		128768 Mtexels/sec
	Difference: 22328 (17%)

Pixel Rate

The Radeon RX 5500 XT should be a lot (approximately 71%) more effective at anti-aliasing than the Geforce GTX 680, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 22752 (71%)

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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
