GeForce GTX 580 vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which has core clock speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 memory. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.

GeForce GTX 580		192384 MB/sec
	Difference: 36992 (19%)

Texel Rate

The Radeon RX 5500 is much (more or less 197%) better at AF than the GeForce GTX 580. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 97552 (197%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5500 is the winner, by far. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 16384 (44%)

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 (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
