Geforce GTX 680 vs Radeon RX 5500 XT

Intro

Compare those specifications to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has set the core speed at 1717 MHz. The GDDR6 RAM works at a frequency of 1750 MHz on this particular card. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

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

Theoretically, the Radeon RX 5500 XT should be just a bit faster than the Geforce GTX 680 overall. (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 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 running with lots of anti-aliasing is important to you, then the Radeon RX 5500 XT is a better choice, 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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
