GeForce GTX 580 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which features a clock speed of 1717 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 128-bit bus, and makes use of a 7 nm design. It is made up of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Radeon RX 5500 XT		130 Watts
GeForce GTX 580		244 Watts
	Difference: 114 Watts (88%)

Memory Bandwidth

As far as performance goes, the Radeon RX 5500 XT should in theory be just a bit superior to the GeForce GTX 580 overall. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce GTX 580		192384 MB/sec
	Difference: 36992 (19%)

Texel Rate

The Radeon RX 5500 XT is a lot (about 206%) better at anisotropic filtering than the GeForce GTX 580. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 101688 (206%)

Pixel Rate

If using a high screen resolution 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 580		37056 Mpixels/sec
	Difference: 17888 (48%)

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

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
