Geforce GTX 680 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which comes with a clock speed of 1717 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 7 nm design. It is made up of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

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

Texel Rate

The Radeon RX 5500 XT should be a little bit (about 17%) better at AF 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 superior to the Geforce GTX 680, by far. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock 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 most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate is also dependant on many 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.
