Geforce GTX 680 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which features 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 Texture Address Units and 32 ROPs.

Geforce GTX 680		192256 MB/sec
	Difference: 37120 (19%)

Texel Rate

The Radeon RX 5500 XT will be a bit (about 17%) more effective at texture 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

If using high levels of AA is important to you, then the Radeon RX 5500 XT is the winner, and very much so. (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 maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
