Geforce GTX 680 vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which features a clock frequency of 1670 MHz and a GDDR6 memory frequency 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 ROPs.

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

Texel Rate

The Radeon RX 5500 is just a bit (approximately 14%) better at texture filtering than the Geforce GTX 680. (explain)

Radeon RX 5500		146960 Mtexels/sec
Geforce GTX 680		128768 Mtexels/sec
	Difference: 18192 (14%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5500 is superior to the Geforce GTX 680, by a large margin. (explain)

Radeon RX 5500		53440 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 21248 (66%)

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 megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
